- On glass, warm sudsy water softens many glues. Rinse and dry.
Adhesive residue on glass is the film left behind by tape, labels, tint film or glue, and most of it won't dissolve in plain water. Glass can take a soak and a gentle scrape with care, so the job is usually straightforward, though a mirror needs its own careful approach. Cured adhesive, such as a label or tint that has been stored hot and humid, is harder to remove, so give it more time.
If you're removing window tint residue, soak it first and then scrape with a dull edge. Mirrors need a lighter touch, so test on a hidden corner and keep liquid from seeping behind the edges. For sticky tape residue on glass, an adhesive remover made for glass and a microfiber cloth do the job.

Step by step
Step 1 of 65 minutes
Scrape off the loose residue
Start by hardening any soft, gummy residue. Harden it with ice or cold water for a few minutes, then scrape gently with a plastic scraper using short back-and-forth strokes.
Don't press hard. Lift the loose bits you can and leave the stubborn film for the next steps.
Careful. Use a plastic scraper, because metal blades can scratch glass.
Step 2 of 6
Pretest on a hidden spot
Test the ammonia on a small hidden corner, such as the inside edge of the pane, before you cover the whole residue. Wait a few minutes and check for any color transfer or change in the glass.
If anything changes, stop and use only the warm sudsy wash on the residue.
Step 3 of 6
Dampen and lay the ammonia pad
Fold a paper towel or cloth into a thick pad about the size of the label or residue. Dampen it with household ammonia and lay it over the residue, using masking tape to hold the pad on vertical glass.
Tip. Press the pad gently so it touches every part of the residue.
Step 4 of 6
Leave the pad and keep it damp
Let the pad sit for 1/2 to 2 hours, depending on how thick and old the residue is. Re-dampen it with ammonia whenever it starts to dry out, because a dry pad stops softening the adhesive.
Check the edge of the residue now and then. When it starts to lift, you're ready for the next step.
Step 5 of 65 minutes
Lift off and sponge with sudsy water
Peel back the pad and lift off any label that has loosened. Scrub what's left with warm water and mild dish soap whipped into suds, using a soft sponge or a nylon pad.
Keep the water warm and wipe the sticky film until the glass feels smooth.
Step 6 of 6
Rinse and dry the glass
Rinse the glass with clean water to remove all the ammonia and soap, then dry it with a clean microfiber cloth. Check it from an angle, since any film or streak shows best that way.
Repeat the sudsy wash on any spot that still feels tacky.
Tip. Wipe in one direction so streaks are easy to spot.

Best products for adhesive residue on glass, windows & mirrors
Look for an adhesive remover made for glass or window film, and pretest it on a hidden corner first. Keep the same rules as the pad, so keep it off mirrors and never scrub with a scouring pad.

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 residue should soften, feel tacky and then slide or wipe away in a film. When the glass looks clear and no longer feels sticky under your fingers, the job is done.
What changes for yours
Adjust for your glass, windows & mirrors
Window tint and film adhesive
Once the film itself is off, the adhesive left on the glass is handled like any other residue, so use the same steps. Work the pad in smaller sections so the adhesive softens evenly and doesn't dry out at the edges. Pretest a small corner first before you work the whole pane.
If a hazy film still shows after the sudsy wash, repeat the pad for another half hour and wipe again. A product made for removing window film adhesive is the next option when the pad isn't enough.
Sticky labels, stickers and tags
Labels and stickers are the easiest version of this job, and the pad method is built for them. Most of the label loosens as the adhesive softens, so lift it slowly with the scraper before you sponge. Don't pull a label while it's still stiff; wait for the adhesive to soften first.
If a paper layer stays behind, put the pad back on it for another round and finish with the sudsy wash.
Sticky tape and double-sided tape
Tape leaves a thin, tacky film rather than a thick glue, so the pad usually needs less time. Start with the scraper under a corner of the tape, then lift it in one slow direction. Keep the pad on the film for about half an hour before you check again.
Double-sided foam tape can leave a stubborn layer on the glass. Once the bulk is off, repeat the pad only on the tacky areas and finish with the sudsy wash.
Mirror adhesive
Skip the ammonia pad on a mirror. Use the warm sudsy wash and the plastic scraper alone, working gently around the edges so the backing stays put.
Let the soft residue sit in the warm wash for a few minutes, then scrape again and rinse with clean water. Dry with a microfiber cloth and wipe in one direction.
Glass jars
Soak the jar in warm sudsy water so the label paper loosens, then peel off what you can by hand. Use the ammonia pad only on the glue that remains, since most labels come off after the soak.
Fill the jar with warm water rather than hot, and let it sit before you scrub. Rinse well and dry the outside as well as the inside.
Glass windows
Windows are flat, vertical glass, so the masking tape step in the pad method works well here. Lay the pad over the residue, tape its edges, and leave it for the full time, re-dampening as needed.
Finish with the warm sudsy wash, a clean water rinse and a dry microfiber cloth. Check the glass from an angle, since haze shows best that way.
Old, dried or set-in stains
Old adhesive that has sat for months or years is harder than fresh residue, and it may not lift in a single round. Start with a longer pad session, up to two hours, and re-dampen the pad as it dries.
If the residue has dried into a hard, glassy film, the ammonia pad may only soften the edges. Repeat the pad once more, then scrape with the plastic scraper, working the edges first.
Adhesive that has been baked by heat, such as glue on a window in full sun, is harder to remove than fresh residue. Don't use hot water or a heat source to soften it, because sudden temperature changes can break glass. If it's still there after two rounds, accept that a thin film may stay, and consider a professional or an adhesive remover made for window film.

Do home remedies work on adhesive residue on glass, windows & mirrors?
Most home remedies were built for fabric, tile or metal, so few of them belong on glass. Only the ammonia pad and warm sudsy wash are needed on glass; the rest are better skipped.

What makes it worse
Mistakes to avoid
Don't mix ammonia with chlorine bleach
Never combine the ammonia pad with chlorine bleach, even as a quick follow-up on the same spot. Rinse all the ammonia off the glass before you use any other cleaner.
Don't use the ammonia pad on mirrors
Ammonia can damage the edges and backing of a mirror, so keep it off. Spraying cleaner directly onto a mirror is a problem for the same reason.
Don't use hot water on cold glass
A sudden temperature change can break glass, so hot water poured onto cold glass is a real risk. Stick to warm sudsy water for every wash here.
Don't scrub glass with scouring pads
Scouring pads are abrasive, and glass needs non-abrasive cleaners with plastic or nylon pads only. Use a soft cloth or nylon pad for the sudsy wash.
Troubleshooting
If the stain is still there
Pick what you're seeing:
The pad dries out before the glue softens.
Add more household ammonia to it and press it back against the glass. A thicker fold holds moisture longer.
The pad keeps slipping off a window.
Add more strips of masking tape across the pad. Anchor every strip on clean glass so it grips.
The residue smears instead of lifting.
It is still too soft. Chill it with ice, then scrape again with light, short strokes.
A faint haze stays after drying.
Wash the spot again with sudsy water and rinse with plenty of clean water. Leftover soap and loosened glue both cause haze.
When to call a professional
If the residue still won't lift after two full rounds with the pad, stop before trying anything stronger. A glass professional can remove it without risking the surface, especially on a mirror or a valuable pane.
Questions
How do I remove adhesive from glass without scratching it?
Use a plastic scraper, never a metal blade, and keep your scraping gentle. Pretest the ammonia on a hidden corner, then finish with the warm sudsy wash, which is the gentlest combination for glass.
Can I leave the ammonia pad on longer than two hours?
Stay within the 1/2 to 2 hour range. If the residue still hasn't lifted at two hours, re-dampen the pad once and check again instead of leaving it longer.
Can I use vinegar instead of ammonia on glass?
Not for this job. No, vinegar-based cleaners shouldn't go on mirrors, and the ammonia pad is what loosens the residue. Use the warm sudsy wash for the finishing clean.
Does super glue come off glass?
Super glue behaves differently from tape and labels, so don't expect the same result. Start with the scraper and the pretest, and stop if the glass starts to change.
Is hot water safe for softening glue on glass?
No. Glass can break from a sudden temperature change, so use warm water and sudsy wash instead of hot water.
Can I use a solvent on glass?
Only after a pretest on a hidden spot, and only in a well-ventilated room. Dry-cleaning solvents are flammable, so keep them away from flames, pilot lights and sparks.
