Dark spots on my smooth double-sided PEI sheet

The printer is in a spare bedroom , heated in winter and with air conditioning in summer. The printer is used about 2 hours a week. The sheet is cleaned exclusively using 90% isopropyl alcohol , So those are absolutely normal conditions.
Is the steel starting to get pitted ?
