How to get slime out of a blanket or sheets

How to remove slime from sheets

1. 1

   Pick off the bulk

   Lift off as much slime as you can with your fingers, a spoon or a dull knife, pulling it up rather than pushing it down. Pressing a larger ball of the same slime onto the spot can pull off smaller bits.

   Why: Slime sticks to itself better than to fabric. The less gel left in the fibers, the less you have to dissolve. The self-lifting trick is common practice, not from a cited source.

2. 2

   Soak the residue with white vinegar

   Lay the blanket flat and pour or spray white vinegar over the remaining slime, enough to saturate it. Let it sit for a few minutes, then blot with a paper towel. On colored fabric, test vinegar on a corner first.

   Why: Slime's stretch comes from borate ions linking the glue's polymer chains. Acid breaks those links, so the gel collapses into a thin, water-soluble liquid.

3. 3

   Work in detergent and rinse warm

   Once the slime has gone runny, rub a little liquid laundry detergent or dish soap into the spot with your fingers, from both sides of the fabric, then rinse under warm running water.

   Why: Once uncross-linked, the glue polymer dissolves in water, and detergent helps carry it out of the weave or pile.

4. 4

   Wash the whole blanket

   Wash the blanket or sheet in the warmest water its care label allows, with your usual detergent. Give a large blanket room in the drum so it can rinse properly.

   Why: A full wash removes the vinegar and loosened residue evenly, so you don't end up with one stiff or clean-looking patch.

5. 5

   Treat leftover color with oxygen bleach

   If colored slime left a tint, soak the area or the whole item in an oxygen bleach solution, following the package. On white cotton sheets labeled bleach-safe, chlorine bleach is an option, but only after the vinegar has been fully rinsed out.

   Why: Slime dyes can bind to fibers like any dye stain, and an oxidizing bleach breaks the color down.

6. 6

   Air-dry and check

   Hang it or lay it flat to dry and check the spot in daylight. Repeat the vinegar and detergent steps if it still feels stiff or looks tinted, then use the dryer.

   Why: Dryer heat dries any remaining polymer into a hard film and sets leftover dye.

Why vinegar dissolves slime

Toy slime is usually polyvinyl alcohol or school glue (polyvinyl acetate) mixed with a borate activator such as borax. The borate ions form weak, reversible bonds between the long polymer chains, and that loose network is what makes slime stretch, ooze and hold together. It's an adhesive stain that wraps around fibers instead of soaking into them.

An acid like vinegar undoes the cross-links, so the gel loses its structure and becomes a runny liquid that water can carry away. The general method across surfaces is on the slime stain page.

Fleece, knits, sheets and comforters

Fleece and plush blankets have a deep pile that slime wraps into, so pick off more of the bulk before adding vinegar and work the detergent in with your fingers along the pile. Sheets are a flat, tight weave, and slime usually lifts off them in big pieces. Comforters and duvets have fill inside: treat the shell fabric with as little liquid as possible, then wash the whole piece only if its label allows and you can dry the fill completely, since damp fill can turn musty.

Check the care label before the wash and bleach steps. The laundry symbols guide explains what each one means.

By situation

Fresh slime

It lifts off in pieces and liquefies quickly with vinegar. Most fresh slime is gone after one round of vinegar, detergent and a wash.

Dried slime

Dried slime behaves like dried glue. Soak it with vinegar or warm water for several minutes to soften it before you scrape, then use detergent. Dried colored slime is more likely to leave a tint that needs the oxygen bleach soak.

It went through the dryer

Heat can turn slime into a hard film. Scrape off what you can, soak the area in warm water with detergent, then use vinegar and the dye method. Complete removal isn't guaranteed.

White sheets versus colored blankets

On white cotton sheets, chlorine bleach (if the label allows) or oxygen bleach removes leftover dye. On colored blankets, use only oxygen bleach, and test vinegar first, because it can shift some dyes.

Wool or silk blankets

Lift off what you can without wetting it and take it to a dry cleaner. Vinegar is an acid, and Michigan State Extension warns that strong acids harm wool and silk.

Glitter slime

Use the same steps. Glitter is loose plastic flakes, so shake the blanket outdoors and lint-roll it once dry to catch the last pieces.

What not to do

• Don't rub the slime before the vinegar has broken it down. Rubbing spreads the gel and its dye deeper into the fibers or pile.
• Don't put it in the dryer until the slime is gone. Heat dries the polymer into a film and sets the dye.
• Don't use chlorine bleach on a spot that still has vinegar in it. Bleach plus an acid releases chlorine gas. Rinse thoroughly between the two.

Other methods that work

Ice

Holding a bag of ice on soft slime firms it so it peels off in bigger pieces, the same principle used for gum. It's a traditional tip with weak evidence, and it only helps with the bulk.

Caution: Follow it with vinegar and detergent for the residue.

Rubbing alcohol

Often suggested for clear-glue slime residue. It's traditional advice with weak evidence for slime, and vinegar has the clearer chemistry behind it.

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

Stain still there?

The spot feels stiff after washing

A thin glue film remains. Soak it with vinegar again, work in detergent, rinse warm and rewash.

A colored ring remains

That's dye, not slime. Soak the blanket in oxygen bleach solution as the package directs, then wash. Test on colors first.

Slime is matted deep in a fleece blanket

Saturate the area with vinegar, wait, then work the residue out in small sections with your fingers before rinsing.

Safety

• Never use vinegar and chlorine bleach together; rinse well between them.
• Keep borax and other slime activators away from small children.

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