Folks, My Mini has developed some serious bubbles between the PEI sheet and the glass. I’ve ordered a new PEI sheet which is on its way. What is the recommended removal method for getting the old sheet off the glass and cleaning the glass in preparation for the new PEI sheet? Cheers, Dan ---

Hey Daniel, There are instructions on replacing the PEI on a Lulzbot Mini [here](https://ohai.lulzbot.com/project/mini-replacing-pei/maintenance-repairs/) I might add (after doing a couple PEI replacements myself) that scraping the glue off the glass can take a while and it might be worth picking up a scraper ([like this one](https://www.bunnings.com.au/kincrome-100-x-40-x-10mm-folding-scraper_p5760288)) to save your fingers some pain. Good luck with it 🙂 ---

Cool, thanks Aidan. I’ll give that a go when the replacement sheets turns up. Cheers, Dan
