Most stainless-steel tableware and many stainless-steel cookware items are dishwasher-safe, but quality and construction vary.
Avoid prolonged contact between stainless steel and silver-plated utensils or certain other metals, as chemical reactions may cause discoloration. Remove stainless-steel items promptly if water spots are a concern.
Can Silicone Go in the Dishwasher?
Many food-grade silicone utensils, molds, and baking tools are dishwasher-safe. Check the manufacturer’s directions because items containing glued parts, metal inserts, or decorative finishes may have different requirements.
Place lightweight silicone objects securely so they cannot block a spray arm or fall onto the heating element.
Can Glass Food Containers Go in the Dishwasher?
Most modern glass food containers labeled dishwasher-safe can be washed in the appliance. Lids may have different care instructions, especially when they contain seals, valves, clips, or plastic components.
Very old, decorative, cracked, or hand-painted glass should be treated more carefully. Sudden temperature changes can also cause some glass objects to crack.
Loading the wrong object can damage more than the item itself—loose labels, melted plastic, and broken fragments may also interfere with the dishwasher’s essential components.
How to Protect Your Dishwasher
Avoiding inappropriate items is not only about protecting dishes and cookware. Loose labels, melted plastics, excess grease, and broken fragments can interfere with:
- Filters
- Spray arms
- Drain pumps
- Detergent dispensers
- Heating elements
Inspect the racks before starting a cycle and make sure nothing can fall through, block movement, or come into direct contact with exposed heating components.
Clean the Dishwasher Filter Regularly
Many modern dishwashers have a removable filter near the bottom of the appliance. Food residue, labels, glass fragments, and other debris can collect there.
Check and clean the filter according to the manufacturer’s instructions. Regular maintenance can improve performance, reduce odors, and help prevent drainage problems.
Use caution when reaching into the filter area because small pieces of broken glass may be difficult to see.
