3. Use & Care

3.1 My slime feels sticky—how do I fix it?

Add one drop of our Activator Spray (included free) and knead for 10 seconds. Repeat until it no longer clings to clean hands.

3.2 It turned stiff or rubbery. Help!

Over-activation or cold weather can firm slime. Work in a few drops of warm water or glycerin and knead slowly to restore softness.

3.3 How should I store slime?

Keep it in its airtight jar, lid fully closed, at room temperature (18–24 °C / 65–75 °F). Avoid direct sunlight or heaters.

3.4 How long does slime last?

With proper care 4–6 months. If it dries out, add water drop-by-drop; if it smells sour, dispose of it responsibly.

3.5 Any surfaces I should avoid?

Yes—fabric, carpet, hair, and porous wood can stain. Play on a clean, smooth table or silicone mat.
