How to get glue out of carpet

How to remove glue from carpet

1. 1

   Identify the glue

   White craft glue, school glue and most wood glues are water-based and dry clear or white. Super glue dries hard and shiny within seconds. Hot glue is a rubbery plastic bead. Glue sticks are soft and may be colored.

   Why: Water dissolves water-based glues; it does nothing to cured super glue, which needs a solvent.

2. 2

   Scrape or chip off the bulk

   Gently scrape the surface with a dull knife or spoon in short back-and-forth strokes. For hot glue or a soft blob, hold a bag of ice on it first until it's brittle, then chip it off.

   Why: Less glue in the pile means less to dissolve. Cold makes thermoplastic and soft adhesives brittle, so they break away instead of stretching.

3. 3

   Water-based glue: vinegar solution, then detergent

   Blot with a cloth dampened in 1 cup white vinegar mixed with 2 cups water, letting it soften the glue for a few minutes. Then blot with 1/4 teaspoon clear dish detergent in 1 cup lukewarm water. For school glue, the detergent solution alone is usually enough.

   Why: Water-based glues swell and redissolve in water. The Carpet and Rug Institute starts white glue with vinegar and school glue with detergent.

4. 4

   Super glue or adhesive: dab on a solvent

   After a hidden-spot test, dab dry-cleaning solvent or nail polish remover onto the glue with a cotton swab or cloth, working from the edge inward. Let it soften, blot or gently lift the softened glue, and repeat. Never pour it.

   Why: Acetone and other solvents soften cured cyanoacrylate. Applying them with a swab keeps solvent off the backing, which it can damage.

5. 5

   Rinse with warm water

   Mist the area lightly with warm water and blot with a dry cloth. Repeat until the spot doesn't feel tacky or soapy.

   Why: Leftover glue film, detergent or solvent stays sticky and attracts dirt.

6. 6

   Weight-dry and restore the pile

   Cover the spot with a pad of paper towels and a weight until dry. Then rub your fingers through the pile to lift it, or vacuum.

   Why: Drying pulls moisture up out of the backing, and fluffing restores the yarns that scraping flattened.

Why the glue type decides the method

White, school and many wood glues are polyvinyl acetate dispersed in water. They stay water-soluble until they dry into a film, and even dried, they soften with a long soak. Super glue is cyanoacrylate, which cures almost instantly into a hard plastic when it meets moisture; water won't touch it, but acetone softens it. Hot glue is a thermoplastic that hardens as it cools, which is why cold helps.

All of these are adhesive stains. The general approach across surfaces is on the glue stain page.

Protecting the carpet while you work

Carpet yarns are tufted into a backing held with latex adhesive, and solvents poured onto carpet can dissolve that backing. Apply every solvent with a swab or cloth, in small amounts. The Carpet and Rug Institute prefers non-acetone remover for nail polish on carpet, because acetone is a strong solvent that can affect dyes, so test it first if you use it on super glue.

Acetone dissolves acetate and triacetate fibers outright. Most US carpet is nylon, olefin or polyester, but check before using it on an unknown rug. For general spot-cleaning rules, see how to clean carpet.

By situation

Wet white or school glue

Blot up as much as you can with damp paper towels, without pushing it down. Then use the detergent solution and a warm rinse. Wet glue often comes out completely.

Dried white or wood glue

Lay a cloth soaked in warm water or the vinegar solution over the glue for several minutes to soften it, then scrape gently and blot. Repeat until the stiff patch is gone.

Super glue on carpet

Let it cure fully, then scrape what you can and use the solvent step. Results vary: the University of Georgia says super glue on fabric can't be removed, while the adhesive maker's guidance relies on acetone. Expect small amounts to soften with patience and large spills to need a professional.

Hot glue

Ice it until it's hard, then chip and lift it off. Any thin film left can be blotted with dry-cleaning solvent.

Glitter or colored glue

Remove the glue first, then treat any color as a dye stain with the detergent solution. Vacuum loose glitter once the spot is dry.

Wool carpet or rugs

Use the water-based steps carefully, test any solvent, and call a professional for super glue on wool.

What not to do

• Don't pour solvent or nail polish remover on the carpet. Solvents can dissolve the latex adhesive that holds the carpet backing together.
• Don't use acetone on acetate or triacetate carpet. Acetone dissolves those fibers.
• Don't scrub or pull hard at dried glue. Scrubbing frays and distorts the pile, and pulling can tear tufts out of the backing.
• Don't use laundry detergent on carpet. It can contain optical brighteners that dye the fibers and leave sticky residue.

Other methods that work

Rubbing alcohol for sticker or tape residue

The adhesive maker lists rubbing alcohol for sticker residue on fabric. On carpet, dab it on with a cloth and blot.

Caution: It can fade some dyes and is flammable. Test it first.

Professional cleaning

For large adhesive spills, super glue that won't soften, or wool and specialty rugs, the last step in the Carpet and Rug Institute's adhesive sequence is a professional.

Caution: Tell them which glue it is.

Stain still there?

A stiff, shiny patch is left after the glue dried

That's a thin glue film. For water-based glue, soften it with a warm-water or vinegar compress and blot. For super glue, repeat the solvent with a swab.

The spot looks dirty a week later

Residue is attracting soil. Rinse with warm water, blot thoroughly, and weight-dry.

The carpet color changed where you used remover

The solvent affected the dye. Stop, blot with plain water, and call a carpet professional about repair.

Safety

• Nail polish remover and dry-cleaning solvent are flammable. Ventilate and keep them away from flames.
• If super glue bonds skin, separate it gently and wash with soap and warm water; get medical care if it gets in an eye.

Never mix cleaning products; see chemicals you must never combine.
