Window cleaner works well.But the best way is to replace the rollers.
Personally I feel the idea around the alcohol drying out the rubber is from the old days. I don't think cleaning rollers with alcohol on a service call once in a while is going to wear them out any quicker. If they need replacing just replace them.
I use stuff called Stoner plastic surface cleaner. I'm sure it has some alcohol init, but it cleans pretty good and my company gets it for us.
I have been using paraffin/kerosene for a while and it works real well.
Whatever
We use lighter fluid for most feed rolls. Seems to do a great job removing oil/dirt/etc, hasn't excessively dried-out any rollers in 13+ years, and doesn't leave a residue after evaporating. Still use 70/30 IPA mix for things like coronas.
Ink Be Gone is what we use and have been using for 15 years or more. It doesn't harm plastic (mostly) but cleans and dissolves toner from rollers. It's also great at getting ink off the white pad of the ADF or anywhere else for that matter. It's from Image Supply.
