First few minutes
Just happened? Do this first
- Treat wet paint first; latex gets very hard to lift after 6 to 8 hours of drying.
- Blot liquid paint with a clean cloth, working from the edges inward.
- Keep solvents away from vinyl, and check the can before you use anything on oil-based paint.
- Lift thick paint with a rounded spoon rather than digging at it.
Clean water and a gentle wash can lift siding paint if you catch it early. Dried paint often won't lift at all, and the material underneath decides how far you can go. Vinyl needs the gentlest handling, since it can't take solvents or bleach, while aluminum, wood, and fiber cement each respond differently.
Vinyl can't take solvents, so don't reach for a stronger product when paint off vinyl siding stays put. If exterior paint is flaking or peeling, scraping will only tear up the surface. Test any cleaner on a hidden patch first, and call a pro if the wall underneath is breaking down.

5 steps
Step by step
Step 1 of 5
Blot and scrape the wet paint
Blot any liquid paint with a clean cloth, working from the edges toward the center so it doesn't spread. Gently scrape thick paint with a rounded spoon or plastic bowl scraper, using light strokes. Latex paint is water-based, so the sponge wash can still lift it while it's wet.
Careful. Don't let latex paint dry before treating it.
Step 2 of 5
Sponge the wet paint
Dampen a sponge in clean water with a little mild dish soap. Work over the wet paint in small sections, wringing the sponge out often so you aren't spreading it around.
Careful. Don't let cleaners or soap dry on the siding.
Step 3 of 5
Rinse with low-pressure water
Rinse each section with a garden hose on low-pressure spray so the soap and loosened paint wash away. Work down the panel so the runoff carries the soap clear of the sections you haven't done yet.
Careful. On vinyl siding, don't aim a pressure washer upward.
Step 4 of 5
Check and repeat once
Let the spot dry, then look at it in daylight. If paint still shows, repeat the soap wash and rinse one more time on that spot only.
Step 5 of 5
Stop when the paint won't lift
If one repeat doesn't lift the paint, stop rather than moving to stronger products on vinyl. Dried or stubborn paint needs the scraping and wood options described further down the page.

Best products for paint on siding, roof & exterior
Pick a plain liquid dish soap, and skip grease removers and furniture polish, which vinyl can't take.
Amazon Basics Microfiber Cleaning Cloths
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on siding, roof & exterior, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
See what to do for what you're seeing →If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
The wet paint should soften and lift onto the sponge in smears or small flakes. Each rinse should run clearer than the one before, and once the spot is dry with no paint showing, you're done.
What changes for yours
Adjust for your siding, roof & exterior
Peeling and flaking paint
Loose, flaking paint changes the order of work, because lifting the loose edges matters more than the soap. Ease the loose pieces off with a rounded spoon or plastic bowl scraper, and don't pry under paint that's still firmly attached.
Once the loose pieces are gone, sponge what's left and rinse it as described above. If the edges lift cleanly, the rest of the paint is usually the easier part.
Latex and oil-based paint
Latex is water-based, so the soap and rinse are the right approach while it's wet. Oil-based paint isn't water-soluble and normally needs the thinner its can recommends, but vinyl can't take organic-solvent cleaners, so thinners stay off vinyl siding.
Acrylic is closest to latex in how it responds to water, so treat it like latex and stop if it won't lift. If oil-based paint won't come off with scraping and the soap wash, get a pro's advice rather than trying a stronger solvent.
Splatter, overspray, and drips
Fresh splatter is the easiest case if it's latex, since it's still wet and sponges off. Dab it rather than rubbing, so the paint doesn't spread across the panel.
Overspray over a large area is the same job repeated in sections, so keep the sponge moving and rinse as you go. A splatter that has dried is a stubborn spot and needs the scraping approach.
Aluminum, wood, and fiber cement siding
Wood is the only material here with its own specific steps. Wipe the spot with a dry cloth right away so water doesn't damage the finish, and use the stronger wood options only on spots that have dried.
For aluminum, keep to the soap and rinse, which is the gentlest option here. For asbestos, ask a pro before anyone touches the siding. Painted brick has its own guide under Concrete, Brick & Driveways, so start there for brick.
Old, dried or set-in stains
Old paint has usually hardened and bonded to the siding, so the soap and rinse won't lift it on their own. That's the point where the quick steps stop working, and it's normal.
On vinyl, scraping is the most you should attempt: use a plastic bowl scraper or stiff cardboard with light strokes and a flat angle. Keep the scraper moving so you don't dig into the panel.
Some dried paint won't come off completely, and that's realistic on vinyl. Once scraping stops lifting paint, rinse the spot and accept a faint line rather than risking the panel.
Vinegar, baking soda, peroxide and more
Do home remedies work on paint on siding, roof & exterior?
Most kitchen remedies don't belong on painted siding, so this list is short. Dish soap is the only one used in the steps, and the rest either don't apply to paint or are off-limits on painted surfaces.

What makes it worse
Mistakes to avoid
Don't reach for solvents or nail polish remover.
Vinyl siding can't take organic-solvent cleaners, nail polish remover, liquid grease remover or furniture polish, even when the paint is oil-based. If the soap and rinse don't lift it, stop rather than trying a stronger product.
Don't mix bleach with ammonia or use it undiluted.
Bleach mixed with ammonia, or with an ammonia-based detergent, releases a toxic gas, so never combine them. Undiluted chlorine bleach is also off-limits on vinyl siding.
Don't use harsh tools or pressure on fiber cement.
Fiber cement siding can be damaged by the tools and cleaners in its caution, so keep to a sponge, mild soap and a low-pressure rinse. If paint won't lift with those, a pro is the right call.
Don't scrub wood with steel wool or wire brushes.
Leftover iron from steel wool or wire brushes reacts with the wood's natural extractives and stains it. A plastic bowl scraper or a clean cloth avoids that risk.
Troubleshooting
If the stain is still there
Pick what you're seeing:
Water does nothing to the spot.
It is likely oil-based. Check the can for the thinner the label recommends, and test that thinner on a hidden spot first.
You cannot get to the paint before it dries.
Wrap oil-based paint in plastic or airtight wrap to keep it from drying. For latex, treat it as soon as you can — after 6 to 8 hours removal becomes very difficult.
Your scraper is marking the finish.
Put the metal down and switch to stiff cardboard, a plastic bowl scraper, or a fingernail. Soften oil-based paint with boiled linseed oil before you try again.
When to call a professional
Bring in a pro for asbestos siding, or whenever paint won't lift and you're tempted to try something stronger. Pressure washing is the job where a pro's experience matters most, since a pressure washer can damage siding in the wrong hands. Ask them to test a hidden spot before starting.
Questions
Can I remove latex paint from vinyl siding with water?
Yes, if you catch it while it's still wet. Sponge it with clean water and a little mild dish soap, then rinse with low-pressure hose spray. Once latex has dried for 6 to 8 hours, removal gets very difficult.
Can dried paint come off vinyl siding?
Sometimes only in part. Light scraping with a plastic bowl scraper or stiff cardboard is the most vinyl can take, and some residue may stay behind. Once scraping stops lifting paint, stop rather than reaching for a stronger product.
Can I pressure wash paint off siding?
It's the riskiest option for paint removal, since a pressure washer can damage siding in the wrong hands. The low-pressure hose rinse in the steps is the safer choice.
Does paint splatter come off siding?
Yes, if it's latex and still wet. Dab it with a sponge and clean water with a little mild dish soap, then rinse. Dried splatter is a stubborn spot, so it needs the scraping approach.
Do vinegar or baking soda help with painted siding?
Not for paint. No, not for paint. Skip vinegar and baking soda on painted siding, since hard scrubbing with baking soda can dull painted surfaces. Stick with soap and rinsing, and use the wood options only on wood. Stick with the soap and rinse, and use the wood options only on wood.
Can I remove oil-based paint from wood siding?
Fresh oil-based paint on finished wood can usually be rubbed off with a cloth saturated in liquid solvent-base wax. Dried paint calls for boiled linseed oil: cover the spot, let it soften, and wipe it up with a cloth dampened in the oil.
