If nonstick pans are properly maintained (no broiler use and no scratch-causing utensils) and hand-washed with a non-abrasive scrubber, they will usually yield excellent results after a quick, soapy suds in warm water. Then, rinse well and thoroughly dry with a towel. Pay attention to the corners where water tends to gather. If you intend to use a nonstick pan exclusively for delicate baking, then lining it with parchment paper or a silicone baking mat will further protect the surface and facilitate cleaning. Uncoated pans should be hand-washed in hot, soapy water, rinsed and thoroughly dried.
