I got myself one of those Anycubic Ultrabase kits at the same time I designed and installed underbed piezo sensors in my Anet A6 (Prusa clone), as I was tired of messing around with glass and hairspray.

Over time, I started getting more and more bed adhesion failures until it was almost constant – this despite following the manufacturers instructions to clean with alcohol. I don’t usually use IPA, I use denatured ethanol as I get it in bulk for cheap for cleaning up my SLA resin prints. I got to wondering if the additives to denature the alcohol causes the issues be leaving behind some sort of residue. I tried IPA instead with the same result.

I got really annoyed as I had some urgent prints to get out, and succumbed to spraying a “frustration layer” of hairspray – still no dice.

Then I resorted to my go-to cleaner for anything that just won’t budge; AMMONIA!

Yes, it stinks. Yes, your wife will wonder if the cat pissed in your office. But it bloody WORKS!
