Why it works
Sticker glue is a soft, tacky adhesive. Scraping or picking at it mostly smears it around. Rubbing alcohol (isopropyl alcohol) dissolves many common adhesives and then evaporates cleanly, which makes it ideal for glass. Oil works differently: it gets between the glue and the surface and softens it so it rolls off, without the drying effect alcohol can have on finishes. Either way, the secret is the same: apply, wait, then wipe.
What you need
- Rubbing alcohol (isopropyl alcohol) for glass and hard surfaces
- A little cooking oil (vegetable, olive or similar) for wood and painted surfaces
- Cotton pads or a soft cloth
- Warm, soapy water and a microfibre cloth
- A plastic scraper or an old gift card (optional)
On glass, mirrors and hard plastic: rubbing alcohol
- Peel what you can. Lift off as much of the sticker as comes away easily. A little warmth from a hair dryer on low for a few seconds helps paper labels peel more cleanly.
- Soak the residue. Dampen a cotton pad or cloth with rubbing alcohol and hold it on the sticky patch for about 30 seconds.
- Wipe it away. Rub gently in small circles. The glue should soften and roll off. Add a little more alcohol if needed.
- Lift stubborn bits. Use a plastic scraper or an old gift card held at a low angle.
- Wash and dry. Wipe with warm, soapy water, then dry with microfibre for a streak-free finish. Our guide to streak-free glass doors covers the finishing touch.
On wood and painted surfaces: a drop of oil
- Test first. Try a little oil on a hidden spot, such as underneath or inside a drawer.
- Apply a few drops. Rub a small amount of oil onto the residue with your finger or a soft cloth.
- Wait a few minutes. Give the oil time to soften the glue.
- Rub it off. Wipe with a soft cloth, following the wood grain. The glue should roll up and come away.
- Remove the oil. Wipe with a cloth very lightly dampened with warm, soapy water, then dry straight away, so the surface is not left greasy.
Test on a hidden spot first, on every surface. Do not use rubbing alcohol on wood, lacquered or painted finishes, because it can dull or soften them: use oil instead. Rubbing alcohol is flammable, so use it in a ventilated room, away from heat and flames, and keep it away from children. Never mix bleach with vinegar or ammonia, and do not combine different removers. Do not use vinegar on natural stone. And do not use a metal razor blade on tempered glass unless the maker says it is safe, because it can scratch.
Common mistakes
- Scraping before soaking. Dry glue smears and can scratch. Let the alcohol or oil work first.
- Using alcohol on wood. It can leave a dull, cloudy patch. Oil is the gentle choice.
- Using metal scrapers or scouring pads. They scratch glass, plastic and finishes. Use plastic.
- Using acetone or nail polish remover on plastic. It can melt or cloud many plastics.
- Forgetting to clean off the oil. Leftover oil attracts dust and leaves a smear.
What professionals use, and why
Cleaners and window cleaners often carry a citrus-based or purpose-made adhesive remover, which dissolves a wide range of glues and is labelled for the surfaces it is safe on. They use plastic scrapers on most surfaces, and only use a blade on glass when they know the glass type and that the maker allows it, because scraping some glass, including many tempered doors, can scratch it. And they always finish by washing off the remover, because residue from the remover can be as sticky as the glue.
In the office
- Windows and glass doors: old event posters, decals and tape leave residue at eye level. Rubbing alcohol, then a squeegee or microfibre finish.
- Glass partitions and whiteboards: tape residue comes off the same way. For marker ghosting, see our guide to erasing whiteboard ghosting.
- New furniture and equipment: labels on desks and monitors are usually wood, laminate or plastic. Test first, and use oil on wood or anything with a delicate finish.
- Asset tags and inventory stickers: check with whoever manages them before removing.
- Sliding glass doors: once the decals are off, the track below is often the dirtiest part of the door. See how to clean sliding door tracks.
If the residue will not shift
Give it longer. Old, baked-on residue may need several minutes of soaking. Lay the dampened pad on it and come back.
Add a little warmth. A hair dryer on low for a few seconds softens old glue. Do not overheat glass, plastic or finishes, and never use heat together with alcohol, because it is flammable.
Try a dedicated adhesive remover labelled for your surface, following the directions and testing first.
On wood, if the finish looks dull afterwards, a furniture polish suited to the finish often restores it. If the finish itself has lifted, that is a refinishing job.
Frequently asked questions
How do you remove sticker residue from glass?
Peel off what you can, then hold a cotton pad dampened with rubbing alcohol on the residue for about 30 seconds and wipe gently in small circles. Lift stubborn bits with a plastic scraper, then wash with warm, soapy water and dry with microfibre.
How do you remove sticker residue from wood?
Use a few drops of cooking oil rather than rubbing alcohol, which can dull a wood finish. Test on a hidden spot, rub the oil into the residue, wait a few minutes, wipe it off along the grain, then remove the oil with a barely damp soapy cloth and dry.
Is rubbing alcohol safe on all surfaces?
No. It is good on glass, mirrors and many hard surfaces, but it can dull or soften wood, lacquered and painted finishes, and some plastics. Test first, and use oil on wood. Rubbing alcohol is also flammable, so use it away from heat and flames.
Can I use a razor blade on glass?
Only if you know the glass type and the maker allows it. Some glass manufacturers advise against scraping tempered glass, which many doors are, because it can scratch. A plastic scraper is the safer choice.
How do you remove tape residue from office windows?
Dampen a pad with rubbing alcohol, let it sit on the residue, wipe it away, then wash the glass and finish with a squeegee or dry microfibre cloth.
What if the sticker residue is very old?
Let the alcohol or oil soak longer, several minutes if needed. A few seconds of low heat from a hair dryer can soften old glue, but never use heat with alcohol. A dedicated adhesive remover labelled for your surface can also help.
