I have a question about silicone molds. I have used mine for about a year now and I haven't had a problem with unmolding till the last 3 batches. Now it suddenly gets stuck to the bottom of the mold and I have a hard time getting the soap out. I checked my recipes over and over again and they seem to be perfectly fine. Also the soap loaf seems to be wetter than usual at the bottom where it gets stuck. The last batch I didn't unmold till 2 weeks later to see if that would improve and it still got stuck. Like I said I haven't had a problem with it in the whole year and now it started acting up. Can silicone mold just get old suddenly? The only other thing I can think of is that the last batch I did before it started acting up was my first batch where I used goats milk, beeswax and honey as ingredients as well as the first batch I stuck in the fridge to avoid overheating due to the sugar content. I appreciate help on this topic. Thank you!
