- ✅ Non-Stick Surface – No soap residue sticks to the mold, so every bar comes out smooth and clean-edged.
- ✅ Hygienic & Bacteria-Resistant – Tested to resist bacteria and fungal growth, making it a safe choice for repeated crafting use.
- ✅ Corrosion-Resistant – Stands up to lye, essential oils, fragrances, and other soap-making ingredients without degrading.
- ✅ Eco-Friendly & Durable – Recyclable, low energy consumption, and built to last through hundreds of batches.
Cleaning & Care Instructions
- First Use: Rinse with warm water or mild detergent before first use to remove any surface dust. A light coating of oil inside the cavities can help with early batches.
- After Each Use: Soak in diluted mild detergent for 10–30 minutes, then wipe clean with a soft cloth. Avoid abrasive scrubbers to prevent scratches. Air dry thoroughly before storing.
- Storage: Store in a sealed box or bag when not in use — silicone can attract dust from static electricity when left exposed.
- Oven Use Note: If using in an oven, center the mold and keep at least 10 cm from the heating element and 5 cm from oven walls.
- Demold Tip: If your mold has factory-cut edges, align the cuts, secure with plastic wrap or rubber bands, then pour your liquid soap mixture in. Once set, simply flex the mold to release.
