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).
