Why
GladWare is made from polypropylene (PP) plastic, which can warp or degrade under high heat and harsh detergents in the dishwasher. The lids often have a softer plastic that may not withstand the heat, leading to warping or loss of seal.
How do you wash GladWare?
Hand wash with warm soapy water and a soft sponge. Avoid abrasive scrubbers. If you must use a dishwasher, place only on the top rack and avoid high heat drying cycles.
