If you suffer from hard-water, this can leave spots on your silicone products after dishwashing. We have this problem and have to hand-wash ours then immediately hand-dry them to remove any remaining water. If that didn't remove the spots, try soaking the item in a solution of half white vinegar and half hot water for about a half hour. Then hand wash and immediately hand dry. Hope this helps, if it applies to you.
The ChefStir silicone spatulas come as a 4 piece set (2 large and 2 small). The larger ones are great for batters, stir-fry's, scrambled eggs or omelets, flipping waffles, and LOTS more. The smaller ones are FANTASTIC for getting condiments out of those small jars. The silicone scrapes everything right away from the sides of jars or batter bowls!
