Clean for the material
Cast iron, nonstick coatings, wood, stainless steel and silicone have different care requirements. A cleaner that works on one material may damage another.
Dry thoroughly
Water left in seams, under rims or on reactive metals can promote corrosion, odor or microbial growth. Dry before closed storage.
Avoid unnecessary abrasion
Abrasive pads can remove finishes, scratch coatings and make cosmetic damage worse. Use the least aggressive method that accomplishes the cleaning job.
Powered tools
Unplug powered appliances before manufacturer-approved cleaning and keep electrical parts away from water unless the manual explicitly says a component is washable or immersible.
Inspect before storage
Loose handles, cracked containers, peeling coatings, damaged cords or other visible deterioration are signs to stop and consult the manufacturer rather than improvise a repair.
