non stick presto electric skillet
A rough surface on a non-stick pan sounds like you have used oil or fat in it at a high heat

You do not need to use oil or fat in a non-stick pan, and doing so may result in the polymerisation of the oil or fat into a rough and tough surface

You can remove this by the normal use of a polyester scrubbing bad (green 3M pads) and dish soap. Normal non-stick surfaces are strong enough to resist polyester scrubbers, but polymerised oil is not. I use broad circular scrubbing patterns to avoid wearing out one spot when "fixing" a non-stick pan
