I recently experienced 1st layer problems with my MK4 - one side of the smooth PEI sheet partially lost adhesion. Therefore I quickly designed this validation model.
This is what it looks like:

I terminated the print at 30% for obvious reasons …

Acetone to the rescue!
Here is the result after cleaning the surface with pure Acetone

Please make sure you pay attention to this warning (directly taken from the documentation):
- “ Acetone should be used sparingly for cleaning, and only be used on the Smooth steel sheet! Never use acetone on the Textured or Satin steel sheet as the surface will be permanently damaged. Never clean the special PA Nylon sheet with acetone, IPA (isopropyl alcohol), or other alcohol-based solvents (window cleaners, Windex, etc.)! This will damage the surface."
Maybe someone finds this useful.
