First few minutes
Just happened? Do this first
- Act while the paint is wet, because latex that has dried for 6 to 8 hours is very hard to remove.
- If you can't treat oil-based paint right away, wrap the item in plastic or airtight wrap.
- Check the can before using any solvent, and test it on a hidden spot first.
Paint on glass is easiest to deal with while it's wet, because water-based latex can be sponged out with water and detergent before it dries. Oil-based paint isn't water-soluble, so it needs the thinner its can recommends instead of soap and water. Once paint has dried, the mark may become permanent, so the first few minutes matter.
Wipe up wet paint on window glass or a mirror with a damp cloth, moving in one direction so you don't smear it. Frosted or etched glass needs a lighter hand, since the texture holds paint and scrubbing can roughen it. If acrylic paint has cured on a window or jar, go slow with a soft plastic scraper, because patience beats force.

5 steps
Step by step
Step 1 of 5
Blot or scrape up the wet paint
Blot any liquid paint with a soft cloth or paper towel, pressing rather than wiping so it doesn't spread. For thick paint, scrape gently with a rounded spoon, working from the edges toward the center.
Tip. Turn to a clean part of the cloth often so you don't drag paint back across the glass.
Step 2 of 5
Wash with mild soap and warm water
Mix mild dish soap into warm water and wipe the glass with a soft cloth. Work in small sections and rinse the cloth often so you aren't just moving the paint around.
Careful. Glass can break from a sudden temperature change, so keep the water warm, not hot, and don't plunge cold glass into it.
Step 3 of 5
Test and apply a non-abrasive cleaner
Test the cleaner on a small hidden spot first, then apply it to the paint. Let heavy soil dwell 3 to 5 minutes per the product label before wiping. For stubborn spots, scour gently with a plastic or nylon pad rather than anything harder.
Careful. Use a non-abrasive cleanser only, with a plastic or nylon pad, because abrasive pads scratch glass.
Step 4 of 5
Rinse the glass thoroughly
Rinse with clean water until no soap film or cleaner residue is left on the surface. Alkaline cleaners may need several rinses, so don't stop after one pass.
Tip. Wipe a finger across the glass: if it feels squeaky clean, the rinse is done.
Step 5 of 5
Dry and check the glass
Dry the glass with a clean, lint-free cloth. Look at it in good light from a couple of angles, and if paint still shows, go back to the wash step instead of scraping harder.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on glass, windows & mirrors, 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 glass should look clear when you view it from a few angles in good light, with no haze or film. If you can see paint along the frame edges or in the corners, go back to the wash step before calling it done.
What changes for yours
Adjust for your glass, windows & mirrors
Window glass and window panes
Window paint usually shows up as drips on the pane or a film along the frame edges, and drips are easiest to lift while they're still soft. Blot the wet drips first, then work the mild soap and warm water over the whole pane from the frame toward the center.
Once the pane is washed and rinsed, look at it in good light and go over any film with the non-abrasive cleaner. Paint caught in the corners of the frame should be worked out with the rounded spoon, not anything harder.
Mirrors
Mirrors need a lighter touch than window glass, because the edges and backing are easy to damage. Dampen a soft cloth with a 50/50 mix of water and rubbing alcohol (isopropyl alcohol) and wipe the paint, working in small sections.
Vinegar- and ammonia-based cleaners stay off a mirror, even on a cloth. If paint remains, repeat the same damp-cloth pass rather than moving to a stronger product.
Oil-based, latex and other paints
Latex is water-based and responds to the wash steps while it's wet, so start there without waiting. Oil-based paint isn't water-soluble, so mild soap won't lift it; it needs the solvent the can recommends as a thinner.
Test any thinner on a hidden spot before using it on the paint. Once it has softened the paint, blot and scrape with the rounded spoon, then return to the wash steps.
Spots, splatter and overspray
Spots and splatter are small, so act quickly with a soft cloth dampened in mild soap and warm water before they dry. Overspray often leaves a faint film, and that film needs the non-abrasive cleaner rather than more water.
For dried specks, keep the surface damp and use the plastic or nylon pad gently, then rinse and check in good light.
Frosted, textured and etched glass
Frosted, textured and etched glass can trap paint in its surface, so the same blot and wash steps apply but need more patience. Test the cleaner on a hidden spot first, since the surface may react differently to it.
Scour only with a plastic or nylon pad and keep the pressure light. If paint stays in the texture after several washes, stop and ask a glass professional rather than pushing harder.
Jars, bottles and drinkware
Drinkware and jars follow the same wash, but the shape makes the rinse harder, so take extra care around the rim and neck. Use the non-abrasive cleanser on a soft cloth and reach for the plastic or nylon pad only when paint is stuck.
Glass and ceramic dishes have their own details, so see our Dishes & Mugs guide for those.
Decorative and window-art paint
Craft and window-art paints vary a lot, and their labels often name a specific thinner or cleaner. Start with mild soap and warm water on a hidden spot, and if it doesn't lift, check the can before trying anything stronger.
If the can names a thinner, use only that one and test it on a hidden spot first. Lift softened paint with the rounded spoon and then go back through the wash steps.
Glass tables, doors and fixtures
Glass tabletops and doors get the same blot, wash and rinse steps, but they're often bigger, so work in sections and rinse as you go. Ornaments and fixtures usually have hardware or painted metal close to the glass, so keep the cleaner off those parts.
When the glass sits in a frame, dampen the cloth rather than soaking the frame, and dry the frame after each pass. If paint remains in a hard-to-reach spot, repeat the wash rather than scraping harder.
Old, dried or set-in stains
Old paint has usually had time to harden, and latex that has dried for 6 to 8 hours is very difficult to remove. Start by keeping the glass wet with mild soap and warm water so the paint softens instead of skidding under the scraper.
Hardened latex can sometimes be scraped off with stiff cardboard or a plastic bowl scraper, held at a low angle and kept wet. For oil-based paint, use the thinner the can recommends, test it on a hidden spot first, and go back through the wash steps after it softens.
If the paint still won't lift after several rounds, stop before the glass takes scratches. A professional glass or window cleaner can take off what's left more safely than you can at home.

What makes it worse
Mistakes to avoid
Don't scrape glass with a razor or metal tool
Metal blades and other hard objects scratch glass permanently. Stick with the rounded spoon and the wash steps, and repeat the wash rather than pushing harder.
Don't spray cleaner straight onto a mirror
Spraying cleaner directly onto a mirror can damage its edges and backing. Dampen a cloth instead and wipe the paint gently with it.
Don't use cleaners with fluorine compounds
Fluorine compounds damage glass, ceramic and stone, so check the label before you use a cleaner. If the label lists fluorine, choose a different product for the glass.
Don't use a solvent without good ventilation
Solvents such as the thinner for oil-based paint need good airflow, and no open flame, pilot light or sparks should be nearby. Open a window and turn off anything that could spark before you start.
Troubleshooting
If the stain is still there
Pick what you're seeing:
Latex paint smears but won't come off
Give the soap solution more time on the spot, then wipe again with a clean section of cloth. A rounded spoon can lift softened edges.
Water does nothing to the paint
It is likely oil-based. Switch to the thinner recommended on the paint can, testing it on a hidden spot first.
A cloudy film remains after cleaning
Leftover cleaner is a common cause. Rinse again with clean water and dry with a fresh, soft cloth.
The mirror has dark marks near the edge
Liquid may have reached the backing, and that damage does not come out. Keep all further cleaning to a barely damp cloth away from the edge.
When to call a professional
If the paint has hardened and the scraping and washing haven't lifted it, a professional glass or window cleaner can remove it without damaging the surface. Ask for one sooner if the glass is an antique, etched, or part of a window that's difficult to take out.
Questions
Does acrylic paint come off glass, and how do I remove it?
Yes, it can come off glass, and it's handled like water-based paint. While it's wet, blot it and wash with mild soap and warm water on a soft cloth, then rinse. If it has dried, scrape gently with a rounded spoon and wash again rather than forcing it with anything harder.
Can I use the same method on frosted or textured glass?
Yes, the blot and wash steps still apply, but test the cleaner on a hidden spot first. Use only a plastic or nylon pad, keep the pressure light, and stop if paint stays trapped in the texture after several washes.
How long can paint sit before it's too hard to remove?
Latex that has dried for 6 to 8 hours is very difficult to remove, so the sooner you start, the better. If it has fully hardened, expect the set-in approach to take several rounds of work rather than one pass.
Do I need a different method for oil-based paint?
Yes. Oil-based paint isn't water-soluble, so mild soap won't lift it on its own. Use the solvent the can recommends as a thinner, after testing it on a hidden spot.
Can I remove craft or window-art paint if I don't know what it is?
Start with mild soap and warm water on a hidden spot, since that's the safest first step for an unknown paint. If it doesn't lift, read the can for a named thinner and use only that one.
Can I use bleach on paint spots on glass?
Use chlorine bleach with care and only as the very last step, after the glass is fully rinsed. Some cleaners need several rinses, so be thorough afterward.
Can I clean paint off a glass table top the same way?
Yes, the same blot, wash and rinse steps work on a table top. Work in sections and rinse as you go so cleaner doesn't dry on the glass.
