When I was a kid a really popular toy was Gak. It was a gooey, slimy substance that you could squeeze, bend, fold, bounce, and pop. It was a lot like Silly Putty, but it had brighter colors and a slimier feel.

I also remember that if you got any dirt on it, you’d never get it off. The Gak would get filthy after a couple of uses.

Maybe that’s how people got the idea to use this gooey slime specifically for cleaning.

That’s right. You’d probably think anything that could be described as “an ooze” would do the opposite of clean, but not only are people using it to clean, they have figured out how to make their own homemade slime.

There are quite a few recipes out there, and most include borax. If you’re concerned about the toxicity of borax, you can also liquid starch (available in the laundry aisle of your local grocery store), and I’ve included that recipe.

To get started, here’s all the ingredients you’ll need:

  • Liquid starch (Sta-Flo, 1/2 cup)*Several sources cite that this is the best liquid starch to use.
  • Elmer’s glue (4 oz. bottle, clear or white)
  • Water (1/4 cup)

For fun enhancements (if you’re making it as a kid’s toy) you can also opt to add:

  • Food coloring
  • Glow-in-the-dark paint
  • Glitter
  • Wiggle eyes, toy critters


  • Bowl
  • Measuring cups
  • Plastic bag
