This isn’t a reply to the above but on the same topic so I hope this is the place to put the question! I use silicone mats when making my resin jewelry for obvious reasons, and they’re great, and big spills come off easily. But I find that after a while the get covered in little drips and smears that aren’t so easy to get off, and worse, make the surface lumpy so that things like doming get very difficult. Any tips on how to clean off all the little bits of dried goo?
