Are Mason Jars Lids Dishwasher Safe?
Most mason jar lids are dishwasher safe, but it’s always best to check the manufacturer’s instructions before placing them in the dishwasher. Some lids may contain rubber or plastic sealants that can warp or lose their adhesiveness in high temperatures or strong detergents. To be on the safe side, wash lids by hand or on the top rack of the dishwasher to prevent damage.
