How to Get Slime Out of Clothes: A Simple Step-by-Step Guide

Slime is one of those kids' activities that's endlessly fun — right up until it ends up on their clothes. Whether it's store-bought slime, homemade goo, or a mystery substance from a school holiday craft session, getting it out of fabric doesn't have to be a disaster. With the right approach, most slime stains come out completely. Here's a simple, step-by-step guide to rescuing slimed kids' clothes.

What You'll Need

• A spoon, butter knife, or old credit card (for scraping)
• Cold water
• Dish soap or liquid laundry detergent
• White vinegar (for stubborn stains)
• A washing machine

Step 1 — Scrape Off the Excess Slime

Before you do anything else, gently scrape off as much slime as possible using a spoon, butter knife, or the edge of an old card. Work from the outside of the stain inward to avoid spreading it further. Be patient — the more you remove now, the easier the rest of the process will be.

Important: Don't rub the slime into the fabric. Scrape, don't smear.

Step 2 — Rinse with Cold Water

Hold the stained area under cold running water to help loosen and flush out the slime. Run the water from the back of the fabric if possible, pushing the slime out rather than further in.

Important: Always use cold water. Hot water can set the stain and make it significantly harder to remove.

Step 3 — Apply Dish Soap or Laundry Detergent

Once you've rinsed off as much slime as possible, apply a small amount of dish soap or liquid laundry detergent directly to the stain. Gently work it into the fabric fibres by rubbing the fabric together — you should start to see the stain lifting almost immediately.

Step 4 — Let It Sit for 10–15 Minutes

Leave the soap to do its work for 10–15 minutes. This gives it time to break down the slime's polymer structure and loosen any remaining residue from the fibres. Don't rinse it off yet — patience is key here.

Step 5 — Wash on a Cold Cycle

Wash the garment in the washing machine on a cold cycle. Once the cycle is done, check the stain before moving on — if it's still visible, repeat steps 3–5 before drying. Never put a stained garment in the dryer until you're sure the stain is completely gone.

Step 6 — Air Dry and Check

If the stain is gone, air dry the garment rather than using the dryer. Heat from the dryer can permanently set any residue that's still present, so it's always safer to line dry and check first. Once you're confident the stain is fully out, the garment is good to go.

Bonus Tip — White Vinegar for Stubborn Slime

For particularly stubborn slime stains, try soaking the affected area in a mixture of equal parts white vinegar and cold water for 15–20 minutes before repeating the soap treatment. Vinegar helps break down the slime and neutralise any sticky residue — and it's a completely natural, chemical-free solution that's safe for kids' clothing.

Prevention Tips for Future Slime Sessions

• Use dedicated play clothes — keep a stash of preloved kids' clothing specifically for messy activities. Quality secondhand pieces are perfect for slime, paint, and craft sessions — and you won't stress if they get stained
• Embrace the mess intentionally — slime is a fantastic form of sensory and messy play with real developmental benefits for kids. Setting up a dedicated messy play space makes it easier to contain — and more fun for everyone
• Use an apron — a simple apron over play clothes adds an extra layer of protection
• Do slime outside or on a hard surface — easier to clean up and less likely to end up on fabric
• Act fast — fresh slime is always easier to remove than dried slime. The sooner you treat the stain, the better

Frequently Asked Questions

Does slime wash out of clothes?
Yes — most slime washes out completely if treated correctly. The key is to act quickly, use cold water (never hot), and apply dish soap or laundry detergent before washing on a cold cycle. Avoid the dryer until you're sure the stain is fully gone.

What removes slime from fabric?
Dish soap or liquid laundry detergent applied directly to the stain works well for most slime. For stubborn stains, a soak in equal parts white vinegar and cold water before the soap treatment is very effective.

Can you use hot water to remove slime from clothes?
No — always use cold water. Hot water can set the slime stain into the fabric fibres, making it much harder (or impossible) to remove.

What should I do if the slime stain won't come out?
Repeat the treatment — apply dish soap, let it sit, and wash again on a cold cycle. For very stubborn stains, try the white vinegar soak first. If the stain persists after multiple treatments, the garment may still be perfectly wearable as a dedicated play or craft outfit.

How do I protect kids' clothes during slime play?
The easiest solution is to keep a dedicated set of "play clothes" — old or preloved kids' clothing that you don't mind getting messy. Add an apron for extra protection, and do slime activities on a hard surface where possible. For more on the benefits of messy play, see our guide on the benefits of messy play for children.
