1. Use Non-Toxic Ingredients
- Always check that all ingredients used in making slime are non-toxic and safe for children.
- Avoid using harsh chemicals, strong adhesives, or borax in large amounts, as they may cause skin irritation.
2. Supervise Young Children
- Always supervise young children while they play with or make slime to prevent accidental ingestion.
- Ensure they follow instructions and use the materials correctly.
3. Avoid Contact with Eyes and Mouth
- Slime should never be put in the mouth, as some ingredients may be harmful if ingested.
- If slime accidentally gets into the eyes, rinse immediately with clean water.
4. Wash Hands After Playing

Slime Storage & Maintenance Guide
Slime is a fun and enjoyable sensory toy, but proper storage and maintenance are essential to keep it fresh and mess-free. Follow these simple tips to extend the life of your slime and avoid any unwanted messes.
Storage & Maintenance Tips:
- Store in an airtight container – This prevents the slime from drying out and keeps it fresh for longer.
- Keep away from fabric and carpets – Slime can stick to and stain fabrics, making it difficult to remove. Always play on a clean, non-porous surface.
- Dispose of properly – When the slime dries out or becomes unusable, do not throw it down the drain. Instead, dispose of it in the trash to avoid clogging pipes.
