This is a warning for anyone attempting this: The PEI removal and replacement process is ''extremely labor intensive''. If you haven’t already bought the spare PEI sheets, save yourself the time and trouble and just order a replacement spring steel sheet with double-sided smooth PEI from Prusa.
Two PEI sheets is about $18 USD, while the spring steel sheet is $30 USD. An extra $12 USD will save you 2+ hours of scraping, scrubbing, and wiping.
