How to wash and disinfect sensory squishies without ruining their soft texture (The Cornstarch Method)

If your toddler loves sensory squishies or mochi toys, you know the horror: after 20 minutes on the rug, they look like a fuzzy lint roller covered in pet hair, dust, and crumbs.

Most parents rinse them under hot water with dish soap, and then they become horribly sticky, attracting even more dirt.

Here is the proper 3-step restoration protocol used by collectors and daycares:

1. Wash with Mild Hand Soap & Cold Water:
2. Lather gently in cold or lukewarm water. Do NOT use hot water (it softens the elastomer surface tension) and avoid harsh detergents.
3. Pat Dry with Lint-Free Paper Towel:
4. Do not air dry on cotton towels, which leave microfibers embedded in the rubber.
5. The Secret Sauce: Dust with Cornstarch or Talc-Free Powder:
6. Drop the dry squishy into a ziplock bag with 1 teaspoon of food-grade cornstarch. Shake for 10 seconds. Buff off the excess with a clean dry brush.

Result: The squishy returns to its original brand-new, silky-matte, non-sticky finish! Takes 60 seconds.
