@antaymonkey Hooray! I'm glad you got it sorted!

I had to regularly clean my Prusa build plate with dish soap and water. I would then chase it with an alcohol wipe and glue stick for good measure. (It was a smooth PEI sticker that was losing its stick.)

I've heard a regular wipe-down with Windex and a microfiber cloth can help maintain the stick. Haven't tried that yet.
