Removing paint from windows can be daunting, whether you’re dealing with accidental splatters from a recent renovation or tackling a more significant project. Fortunately, several methods can help you achieve a clean, paint-free finish.
All Clean London covers various techniques, focusing on safety and effectiveness, to help you remove paint from glass and window frames.

Warm Vinegar Solution
Distilled white vinegar is an effective and natural paint solvent that avoids harsh chemicals. Here’s how to use it:
- Heat one cup of white vinegar in the microwave until it boils.
- Wearing thick rubber gloves, soak a clean rag in the hot vinegar.
- Press the soaked rag against the paint stains for a few minutes.
- Scrub the paint away using the rag.
- Clean any remaining paint and vinegar with soapy water and a fresh cloth.
Pro Tip: Use this opportunity to clean your microwave, as the vinegar steam helps loosen food residue.
Soapy Water & Razor Blade
When used carefully, a razor blade can be an effective tool for removing more stubborn paint spots. Begin by wetting the window with soapy water to lubricate the surface. Then, hold a razor blade at a 45-degree angle and gently push it across the glass in long, straight strokes.
Avoid moving the blade back and forth to prevent scratching. This method is particularly effective for removing dried latex paint.
Rubbing Alcohol for Water-Based Paints
Rubbing alcohol is particularly effective for removing water-based paints such as acrylic or latex.
Simply dampen a cloth, toothbrush, or cotton swab with rubbing alcohol and gently scrub the paint in circular motions. Once the paint starts to lift, use a glass cleaner to wipe away any remaining alcohol and paint residue.

How to Remove Dried Paint from Windows
Fine Steel Wool
Using fine steel wool can help break apart dried paint without scratching the glass.
- Wet and Scrub: Wet the window with soapy water and gently scrub with the steel wool in circular motions.
- Rinse: Use a squeegee or clean cloth to wipe away the soapy water and loosened paint.
Acetone or Nail Polish Remover
Acetone is another powerful solvent that works well on wet and dry paint.
- Apply Acetone: Soak a clean rag or cotton ball in acetone and press it against the paint.
- Wait and Wipe: Let it soak for 2-3 minutes, then wipe away the paint with a dry cloth.
Remember to work in a well-ventilated area and wear protective gear, as acetone fumes can be harmful.
How to Remove Paint from uPVC Window Frames
UPVC window frames require gentle yet effective cleaning methods to avoid damage. Start by gently scrubbing away the paint with warm, soapy water and a soft cloth. If the paint is stubborn, use a plastic putty knife instead of metal to prevent scratching the UPVC surface.

Using Mineral Spirits
Mineral spirits are effective for removing fresh paint. The thin spirit makes wet paint easier to remove. Dampen a clean rag with mineral spirits and hold it over the paint marks for a few minutes.
After the paint has softened, wipe it away with a clean corner of the cloth. Wear safety glasses, a face mask, and rubber gloves to avoid irritation or contact with the mineral spirits. Remember that mineral spirits are flammable, so keep them away from heat sources or open flames.
Turpentine for Slightly-Dried Paint
Turpentine works great for breaking down oil-based and water-based paint that has started to dry but hasn’t completely hardened yet. Wet a clean cloth with turpentine and hold it against the paint marks on your window for a few minutes.
Then, wipe the paint marks away with a clean cloth. Make sure to wear safety glasses, rubber gloves, and a respirator to protect yourself from spills and fumes.
How to Remove Paint from Wooden Window Frames
Using a paint stripper can be very effective when dealing with window frames, especially if you want to repaint. Solvent-based strippers work well on both wood and metal window frames by breaking down the bond that holds the paint, making it easier to scrape away.
First, remove any hardware from the frame and lay a tarp to protect the surrounding area. Apply the stripper with a paintbrush and let it saturate the surface for about 20 minutes. Use a scraper to remove the treated paint, and continue this process until all paint layers are removed.
Finish by sanding the window pane with 220-grit sandpaper to work away any small scrapes and remaining paint flecks.

Your Solution for Spotless Windows
With the right methods and tools, removing paint from glass can be straightforward. Using natural solutions like vinegar and more robust methods like acetone, you can restore your windows to their original clarity.
Always remember to wear protective gear and work in a well-ventilated area when dealing with chemical solvents. By following these tips, you can ensure your windows and window frames remain clean and paint-free, enhancing the overall appearance of your home or business.
