Hey All,
How do you guys clean your moulds after a pull?
I'm currently using the uni mould system with resin infusion along with easy-lease for my release system.
Before I create another part I need to clean off some glue residue and some hardened epoxy around the edges. As Im using a semi perm release agent I don't want to use anything too harsh as I don't want to have to start from scratch adding 6 or so layers again.
Ive tried some all purpose cleaner so far but, its not cleaning the mould up so well. Any suggestions?

You can buy plastic razor blades that work ok and won't scratch. I've also found that a wood or hard plastic piece with a hard corner held almost 90 degrees to the surface scraper-style can remove stuck flash without scratching the mold - only something you want to do on your flanges not in the actual part zone. Spray adhesive - not so much - only mold cleaner or some other nasty solvent seems to work.
