So I've got a ton of resin to clean and not the time. I went and bought a 1.5L tank Sonic Cleaner on eBay for about AU$130. I used warm water and it did nothing! Soaked the stuff in 1:1 ratio simple green for a week and half THEN threw it in and still the mold release still won't come off.

Think I have to go back to tooth paste and a soft brush.

Has anyone else used a sonic cleaner for this purpose?
