Title sums it up, any other tips about PETG appreciated though.
I’m not using anything specific for PETG clean up. IPA to get rid of oily residue and soapy water from time to time.
I use textured PEI, and this is pretty much my regimen for PETG as well. So far, a thorough 90% IPA wipe with a lint-free towel or microfiber right before each print is all I have ever needed to get good adhesion.
Honestly this is the way for pretty much all surfaces, exception if the surface tells you not to use certain cleaners (I have one that says to not use soap, only IPA).
I’ve never really thought much about something specific for petg.
I use a magnetic pei bed, both textured and non textured with a glue stick layer.
I don’t often need to clean but I’ll use soap and water in the sink for the majority and then a isopropyl squirt and rub with a rag. Then I reapply glue stick.
This lasts a lot of prints for me for pla, petg and abs.
Really, I’d think you would need to avoid chemicals that would react with your bed and make sure there is no residue left by your cleaner. For my pei bed I bet I could even use acetone. Beyond that… Happy washing.
There are lots of internet gudes on this. Here is one random one I just found. https://www.wevolver.com/article/how-to-clean-3d-printer-beds-glass-pei-adhesive
Why do you ask? Are you seeing some sort of residue? I’ve never heard of PETG leaving anything behind, just being REALLY stuck and pulling up some of the surface, I think. I’ve no personal experience.
I have printed lots and lots of parts in PETG and not once did anything special to the bed after a print.
Regarding other tips about PETG: make sure the filament is dry. Wet PETG will pull lots of strings, no matter how “good” you’re tuning your retractions.
