Chemical stripper, heat gun or sanding — what each one is genuinely good at, how to use it safely, and how to get paint out of mouldings without destroying the detail.
There are only three real ways to get paint off wood: dissolve it, soften it with heat, or abrade it away. Everything else is a variation on one of those.
Most people default to sanding because they own a sander. That is often the worst choice. Sanding thick or soft paint clogs abrasive in seconds, throws dust everywhere, and rounds over the crisp edges and mouldings that give old woodwork its character.
Here is the short version of what actually works:
- Chemical stripper — best for detailed mouldings, carvings and many layers. Slow but gentle on the wood.
- Heat gun — fastest for thick paint on flat surfaces like doors and skirting. Free to run once you own the gun.
- Sanding — best for thin, sound paint and for the final clean-up after either of the other two.
Most real jobs use two of them together. This guide shows you which to pick, how to use each properly, and the safety points that genuinely matter. 💡

Read This First: Lead Paint
This is the one section you should not skip, because it changes which method you are allowed to use.
Paint made before 1978 may contain lead. Lead dust and lead fumes are genuinely dangerous — particularly for children under six and anyone pregnant. Old woodwork in older homes very often has lead somewhere in the layers, even under newer paint.
Test before you start. Lead test swabs are inexpensive and available in any hardware shop. Score through all the layers first so the swab reaches the oldest paint, not just the top coat.
If it tests positive:
- ❌ Do not sand it. Sanding creates fine lead dust that spreads through the house and is very difficult to clean up.
- ❌ Do not use a heat gun above about 1,100°F. High heat vaporises lead into fumes you then breathe.
- ✅ Chemical stripping is the safest DIY route, because the paint comes away as wet sludge rather than dust or fumes.
- ✅ Better still, consider a professional. Lead-safe certified contractors have containment and disposal procedures for exactly this.
The Three Methods Compared
| Method | Speed | Best surface | Damage risk | Mess | Lead-safe? |
|---|---|---|---|---|---|
| Chemical stripper | ⚠️ Slow (hours) | Mouldings, carvings, many layers | ✅ Very low | ⚠️ Sludgy | ✅ Safest option |
| Heat gun | ✅ Fast | Flat doors, skirting, frames | ⚠️ Scorching, fire | ✅ Low | ❌ No — fumes |
| Sanding | Moderate | Thin sound paint, flat areas | ⚠️ Rounds detail | ❌ Heavy dust | ❌ No — dust |
| Scraping (hand) | Slow | Loose flaking paint | Low if careful | ✅ Low | ⚠️ With care and wet methods |
The fastest job is almost never one method. It is heat or chemicals to remove the bulk, then light sanding to clean up what is left.
Chemical Strippers, Done Properly
Chemical strippers work by breaking the bond between the paint film and the wood. The paint softens, wrinkles and lifts, and you scrape it away. The wood underneath is untouched — which is exactly why this method is the right choice for anything with detail worth keeping.
What is in them now
The market has changed significantly. Methylene chloride was the traditional fast-acting stripper, and it is now banned for consumer paint removal in the United States following EPA action — it caused deaths in poorly ventilated spaces. Products sold today are generally based on gentler chemistry: benzyl alcohol, dibasic esters, or citrus-derived solvents like d-limonene.
The practical trade-off is simple. Modern strippers are far safer and much slower. Where the old products worked in fifteen minutes, these want several hours — sometimes overnight. Plan around that rather than fighting it.
How to use one well
- Ventilate. Open windows, and work outdoors if you can. Low odour does not mean no fumes.
- Wear the right gloves. Thin disposable gloves dissolve. Use chemical-resistant nitrile or butyl gloves, plus eye protection.
- Protect the floor with plastic sheeting, not newspaper — strippers soak straight through paper.
- Apply thickly in one direction. Use an old brush and lay it on like icing. Do not brush back and forth — that breaks the surface and lets it dry out.
- Cover it. Laying cling film or plastic sheet over the gel stops evaporation and keeps it working for hours longer. This single step roughly doubles effectiveness on thick paint.
- Wait properly. Check after an hour. The paint should be wrinkled and soft all the way down. If it is not, wait longer — scraping early just means doing it twice.
- Scrape gently with a plastic or dull metal scraper. Work with the grain. Let the softened paint come to you.
- Repeat for stubborn layers. Old woodwork can have eight or more coats. A second application is normal, not failure.
- Neutralise and clean exactly as the product instructs — usually mineral spirits or water. Skipping this leaves residue that stops your new finish curing.
- Let it dry fully before sanding or finishing. Water-based cleanup raises the grain, so allow drying time.
Heat Guns, Done Safely
A heat gun softens paint until it bubbles, and you scrape it off while warm. On a flat surface with thick old paint, this is by far the fastest method — and once you own the gun, it costs nothing to run.
How to do it
- Set a moderate temperature. Hotter is not better; it scorches wood and increases fume risk.
- Hold the nozzle 50–75mm (2–3 inches) from the surface and keep it moving constantly in small circles.
- Work in small sections, roughly 15cm square. Heat one area while scraping the previous one.
- Scrape with the grain as soon as the paint bubbles. Do not wait for it to smoke.
- Use shaped scrapers for mouldings — a set of profiled blades pays for itself immediately.
Never use a heat gun near glass. Window panes crack from uneven heating, and replacing old glass costs far more than the time you saved. Use a heat shield attachment, or strip glazing bars chemically instead.
Sanding Paint Off Wood
Sanding is the method everyone reaches for first and the one that suits the fewest situations. It genuinely works when the paint is thin, hard and sound, and on flat surfaces where there is no detail to lose.
Where it struggles:
- Thick or soft paint clogs abrasive within seconds, so you spend more on paper than on stripper.
- Mouldings and carvings get rounded over, and that detail never comes back.
- Dust goes everywhere, and if there is lead in the layers it is genuinely hazardous.
If you do sand, start at 80 grit and use a random orbital sander on flat areas, with a detail sander for corners and profiles. Keep the pressure light — pressing harder just heats the paint and turns it gummy. Our grit chart covers the full sequence.
The realistic role for sanding is cleanup. Once heat or chemicals have taken off the bulk, a light sanding removes the last traces and prepares the surface. That is where it genuinely shines.
Which Method for Which Job
| The job | Best method | Why |
|---|---|---|
| Panelled door, many layers | Heat gun + scraper | Fast on flats; chemicals for the mouldings |
| Carved or detailed furniture | Chemical stripper | Preserves every detail; sanding would destroy it |
| Skirting boards and architrave | Heat gun | Long flat runs, quick progress |
| Window frames with glass | Chemical stripper | ❌ Heat cracks glass |
| Confirmed lead paint | Chemical stripper | No dust, no fumes — wet removal |
| Thin, sound paint on a flat panel | Sanding | Quick and no chemicals needed |
| Spindles, chair legs, turnings | Chemical stripper | Reaches into shapes no tool can follow |
| Outdoor furniture, flaking badly | Scrape then sand | Loose paint scrapes off with little effort |
| Final cleanup, any method | Light sanding | Removes residue and prepares the surface |
Stripping a Door, Step by Step
A panelled door is the classic project, so here is the whole thing as one worked example using a combined approach.
Step 1 — Take the door off and lay it flat
Work horizontally. Gravity keeps stripper on the surface instead of running down your arms, and scraping is far easier. Rest it on trestles at a comfortable height.
Step 2 — Test for lead
Score through all layers and test. If positive, chemical stripping only, with full containment.
Step 3 — Remove the hardware
Handles, hinges, escutcheons, letter plate. Bag and label the screws. Stripper attacks metal finishes, and paint hides around fittings you leave on.
Step 4 — Do the flat panels with heat
Assuming no lead: work in small sections, keep the gun moving, scrape with the grain as the paint bubbles. The large flat areas go quickly.
Step 5 — Switch to chemical stripper for the mouldings
The profiled edges around each panel are where heat and scrapers do damage. Brush stripper on thickly, cover with cling film, and leave it while you work elsewhere.
Step 6 — Scrape the mouldings with shaped tools
Use profiled scrapers, or improvise with a wooden dowel sharpened to match the curve. Avoid metal points — they leave permanent dents in softened wood.
Step 7 — Second application where needed
Corners and deep profiles usually need another go. This is normal on doors with decades of repainting.
Step 8 — Neutralise and clean
Follow the product instructions exactly. Wipe down, then let the door dry completely — at least overnight, longer in damp weather.
Step 9 — Light sand to finish
Random orbital at 120 on the flats, detail sander or hand sanding on the profiles, then 180 overall. You are removing residue and smoothing raised grain, not stripping.
Step 10 — Inspect before finishing
Wipe with mineral spirits. It darkens the wood the way a finish will and reveals any remaining paint in the grain — much easier to fix now than after the first coat.
Mouldings, Carvings and Awkward Shapes
This is where paint removal is genuinely difficult, and where the wrong approach does permanent damage.
Never use a metal scraper point on softened wood. Once paint is chemically softened, the wood beneath is often slightly softened too. A sharp steel corner leaves a dent that will show through your finish forever.
Better tools for shaped work:
- Profiled scraper sets — cheap, and shaped to match common mouldings.
- Wooden dowels and offcuts — sharpen to match your specific profile. Soft enough that they cannot dent the wood.
- Brass or nylon brushes — brass is soft enough not to score wood, and gets into grooves. Never use a steel wire brush on wood; it tears the grain.
- Coarse twine or string — pull it back and forth in a deep groove to drag softened paint out. Old-fashioned and remarkably effective.
- Cotton buds and toothpicks — for tiny carved details, worth the patience.
For turned legs and spindles, apply stripper, wrap the whole piece in cling film, and leave it for several hours. Then wipe down the length with coarse twine or a rag. Sanding a turning is nearly impossible without flattening the crisp rings that make it look right.
What to Do After the Paint Is Off
Getting the paint off is not the finish line. What you do next decides how the wood looks.
Neutralise properly. Stripper residue left in the grain stops new finishes curing — you get permanently tacky patches. Follow the product’s instructions rather than guessing.
Let it dry fully. Water-based cleanup soaks in and raises the grain. Give it 24 hours minimum, longer in cool or humid conditions.
Expect some staining. Old paint often leaves colour in the grain, especially on oak, and old nail holes can bleed dark rings. Decide whether that reads as character or as a problem. If you want it gone, oxalic acid wood bleach handles iron staining well.
Sand lightly and evenly. 120 then 180 for paint. If you plan to stain the wood, the rules change — read that guide, because stripped wood absorbs stain unevenly if you are not careful.
Fill and repair. Now is the time for filler in old holes and splits, once you can actually see the wood.
Common Mistakes (and How to Fix Them)
Mistake 1 — Scraping stripper too early
What happens: the top layer comes off, the lower ones stay, and you apply it all over again.
The fix: wait until the paint is wrinkled all the way down. Test a small area with a scraper corner first.
Mistake 2 — Applying stripper too thinly
What happens: it dries out in twenty minutes and barely works.
The fix: lay it on thick, in one direction, and cover with cling film.
Mistake 3 — Overheating with the heat gun
What happens: scorched wood that shows through any clear finish, plus fire risk.
The fix: moderate heat, constant movement, scrape as it bubbles rather than waiting for smoke.
Mistake 4 — Aiming a heat gun into a gap
What happens: smouldering debris inside a wall cavity, sometimes hours later.
The fix: never direct heat into gaps. Re-check the area an hour after finishing.
Mistake 5 — Sanding lead paint
What happens: hazardous dust throughout the house.
The fix: test first. If positive, strip chemically or hire a certified professional.
Mistake 6 — Using cheap gloves
What happens: they dissolve and you get stripper on your skin, which burns.
The fix: chemical-resistant nitrile or butyl gloves, and rinse immediately if you get any on you.
Mistake 7 — Skipping neutralisation
What happens: your new finish stays tacky and never fully hardens.
The fix: follow the product’s cleanup instructions precisely, then let it dry fully.
Mistake 8 — Denting softened wood
What happens: permanent marks from a metal scraper corner.
The fix: round off the corners of your scraper with a file, and use wood or plastic tools on detail.
Pro Tips Worth Knowing
Work horizontally whenever you can
Take doors off, lay drawers flat, remove what you can from the wall. Stripper stays where you put it and scraping is far less tiring.
Combine methods without guilt
Heat for the flats, chemicals for the details, sanding for the cleanup. There is no prize for using one method throughout.
Round off your scraper corners
A few strokes with a file turns a gouging tool into a safe one. Keep the edge sharp but the corners blunt.
Collect the waste as you go
Scrape directly into a metal container or onto plastic sheeting. Softened paint sludge sets hard and is far harder to clean up later. Check local rules for disposal, especially with lead.
Do a test patch first
Always try your chosen method somewhere hidden — the back of a door, inside a cupboard. You learn the timings and discover any surprises before they matter.
Give it more time, not more force
Almost every paint-stripping frustration comes from impatience. Longer dwell time, a second application, and gentle scraping beat force every time — and force is what damages wood.
The Stripper I Recommend
For home use — especially anything with mouldings, carvings or confirmed lead — a modern low-odour gel stripper is the sensible choice. It is slower than the banned solvents of the past, but it works safely indoors and it will not damage the wood underneath.
CitriStrip Paint and Varnish Stripping Gel, 17 oz
Best for Indoor and Detailed Work★★★★☆ 4.3 out of 5 on Amazon
This is the stripper most people reach for now that the harsh methylene chloride products have gone. The reason it works well for home projects is the gel consistency — it clings to vertical surfaces and sits inside mouldings instead of running off, which is exactly where you need dwell time.
It is low odour enough to use indoors with the windows open, which genuinely matters when you are stripping a door frame you cannot remove. It stays wet and active for hours rather than flashing off in minutes, so it can work through several layers in one application — particularly if you cover it with cling film.
Why it works:
- ✅ Clings to vertical surfaces and stays in mouldings — no running off the job
- ✅ Low odour makes indoor work realistic where older strippers did not
- ✅ Long working time means it can cut several layers in one go
- ✅ Gentle on wood — no scorching, no rounded detail, no dust
- ✅ The safest DIY route for lead paint, because removal is wet rather than airborne
- ⚠️ Slow by design. Expect hours, not minutes — plan the job around dwell time
- ⚠️ Still needs proper gloves. Low odour is not the same as harmless; use chemical-resistant gloves and eye protection
Best for: panelled doors, carved and turned furniture, window frames near glass, spindles, and any surface where you want to keep crisp detail.
Not for: people in a hurry, or huge flat areas where a heat gun will be far quicker.

Frequently Asked Questions
What is the easiest way to remove paint from wood?
It depends on the surface. On flat areas like doors and skirting, a heat gun with a good scraper is fastest and cheapest to run. On anything with mouldings, carvings or turnings, a gel chemical stripper is far easier, because it reaches into shapes no tool can follow and does not round off detail. Sanding is the easiest option only when the paint is thin, hard and on a flat surface — otherwise it clogs abrasive and creates a lot of dust.
Is it better to sand or strip paint off wood?
Strip first, sand second — that is usually the right order. Stripping removes the bulk without damaging the wood or creating dust, and light sanding afterwards cleans up residue and smooths raised grain. Sanding alone is only sensible on thin, sound paint on flat surfaces. If there is any chance of lead, sanding is not an option at all.
Does vinegar or baking soda remove paint from wood?
Not reliably, despite how often these appear online. Heated vinegar can soften some water-based paints slightly, and baking soda boiling is sometimes used on small metal hardware — not wood. On wood, both add moisture that raises the grain and can cause staining, while barely touching modern paint. For actual results, use a purpose-made stripper, a heat gun, or abrasives.
How do I remove paint from detailed mouldings without damaging them?
Chemical stripper, applied thickly and covered with cling film, then removed with non-metal tools. Shaped plastic scrapers, sharpened wooden dowels, brass brushes and even coarse twine pulled through grooves all work well. Avoid steel points entirely — softened wood dents permanently. Expect two applications on deep profiles; that is normal rather than a sign something has gone wrong.
Can I use a heat gun on lead paint?
No — not safely. Heating lead paint above roughly 1,100°F vaporises the lead into fumes, which is more dangerous than the dust from sanding. If a lead test is positive, use a chemical stripper so the paint comes away as wet sludge, contain and dispose of the waste properly, or hire a lead-safe certified contractor. Test first, before you choose any method.
Why is my new finish still tacky after stripping?
Almost certainly stripper residue left in the grain. Chemical strippers must be neutralised and cleaned exactly as the product specifies — usually with mineral spirits or water — and then allowed to dry completely, which can take a day or more. Residue interferes with curing, so the finish stays soft indefinitely. The fix is to strip the tacky finish back off, clean the wood thoroughly, let it dry properly, and refinish.
