For your resin trays and other resin items- do not place in a dishwasher. If the item gets dirty, just wipe it off with a damp cloth. Do not leave in direct sunlight. Resin items continue to harden for about a month after they are cured. Curing takes about two to three days. Although the resin is non-toxic, it is not considered food-grade. If you want to place food on the tray, put a plate or napkin underneath. A warm cup can be placed on the resin tray or coaster. But avoid placing very hot items on the surface of a resin tray or coaster.
