DIAGNOSIS You're almost certainly using an abrasive—metal utensils, steel wool, scouring pads, or even some harsh dishwasher detergents. The coating is delicate.
FIX Stop the damage now. Hand-wash only with a soft sponge or cloth and mild dish soap. For stuck-on grease, soak the basket in hot, soapy water for 20 minutes, then gently wipe. Never use metal utensils inside; use silicone, wood, or nylon.
IF THAT DIDN'T WORK If the peeling is extensive and flakes are getting on your food, the basket is a safety hazard and needs replacement. Contact KMFurnila for a replacement basket. Do not try to re-coat it yourself.
HEADS UP Even small flakes of non-stick coating are not safe to ingest. If you see any peeling, inspect food carefully before eating. A fully peeled basket will also cause severe sticking and smoke.
