How to Take Care of Silicone Moulds to Make Them Last Longer (Without Losing Your Mind in the Process)

I remember the first time I broke one of my favourite moulds: it was one I used for making jewellery with encapsulated petals. I was in a rush, pulled too hard… crack. A tear along the side—and goodbye, mould.

Since that day, I’ve learned that taking care of silicone moulds is essential if you want them to last and avoid nasty surprises.

🧼 How to Demould Without Damaging

One of the most common mistakes is rushing the demoulding process, thinking that “faster = better”.
But the real secret is patience and gentle movement.

If your mould fits like a sock, twist it gently while slowly pulling.
💡 This trick has saved me countless moulds in the workshop!

🧽 Tips for Cleaning Silicone Moulds Properly

Cleaning your mould after every use is crucial.
Use lukewarm water and mild soap. Avoid abrasive sponges, alcohol, or harsh cleaners—they can dry out and damage the silicone surface.

📦 How to Store Silicone Moulds
Don’t bend them, don’t stack them, and keep them away from dust and heat.
If you need to stack them, place tissue paper between each mould.
The ideal solution? Store them flat in a dry, dust-free place.

🔒 What to Do to Make Them Last Longer
Use compatible materials and make sure the resin is fully cured before demoulding.
Even a small mistake can cause stains or tears.
The one detail that makes the difference? Patience.

⚠️ Why Moulds Get Damaged (and How to Prevent It)
The most common causes include:

• Rushing or pulling too hard during demoulding

• Using abrasive products

• Improper storage (folded or under weight)

• Exposure to heat or harsh chemicals

👉 Knowing these risks is the first step to protecting your investment.
