How to Remove Adhesive from Glass: Dos and Don'ts

It can be highly beneficial to know how to remove adhesive from glass. It can be incredibly annoying to peel off a price sticker from a piece of glass and find an adhesive mark left on the surface. There are other types of adhesive that can also stick to glass, especially if children prefer applying their sticker collections onto mirrors instead of inside their stickers books. Luckily, removing glue can be relatively simple.

Step 1 - Clean the Glass

Spray glass cleaner onto the surface of the glass and clean it thoroughly with a paper towel. Let it dry fully before proceeding.

Step 2 - Solvent

Take your solvent of choice; it can be nail polish remover, lighter fluid, acetone or even engine penetrating oil. Soak a paper towel in the solvent and place it on the adhesive. This will allow it to soften. Leave it in place for several minutes and remove the towel.

Take the single-edged razor blade and gently scrape off the adhesive. You might need to repeat the procedure with the solvent two or three times before you remove it all. To finish, use glass cleaner again and dry with a clean paper towel. The glass should shine brilliantly afterward.

Step 3 - Things You Shouldn't Do

There’s a technique in knowing how to remove adhesive and, importantly, this includes things you shouldn’t do. If you’re getting adhesive off of glass that’s part of a picture frame or a mirror, you need to make sure you don’t scrape or use solvent on any other areas or you could damage the decorative surrounds.

You also need to be sure you only use a single-sided razor blade. If you do buy double sided blade, you also need a holder into which you can slide the blade for your own safety.

Don’t use solvent near an open flame and don’t smoke when using these materials. Solvents are flammable and the last thing you want to deal with is a fire. Also, don’t work in a small, unventilated room. Again, this is for your own safety because solvents can emit highly toxic fumes.

Step 4 - Things You Should Do

When you’re using a razor blade to remove adhesive, always make the stroke away from you. If you don’t, it’s always possible that the blade could slip and you could end up injuring yourself.

If you’re cleaning adhesive off glass where there are other materials present, such as a picture frame, you can make life easier for yourself by using masking tape on the surrounding area. Not only does it stop solvent from seeping onto other materials, but it also stops you accidentally scraping them with the razor blade. It pays to keep a stock of fresh razor blades to hand. The edges dull very quickly, and you’ll achieve a much better and faster result with a sharp blade. Don’t keep using a dull blade as you may cause damage to the surface you are working on.

Always give solvent time to soak into the adhesive. Generally, this should happen in a few minutes but on the first pass, you might want give yourself 15 minutes to be sure the adhesive has been soaked all the way through by the solvent. This might seem like a long time but it will mean less effort to remove the adhesive afterwards.
