Most products purchased after 9/3/79 are made to be dishwasher safe. Refer to the product insert or look for dishwasher symbol on bottom of each product to determine whether it’s dishwasher safe and if it is, which rack it should be placed on. To prevent odors and staining, it is also beneficial to rinse with cold water immediately after use. Avoid the use of abrasives, including baking soda, which may dull the finish.
