Some background: I've got a drum for a Brother MFC-8710dw that has some streaks. As per the instructions I've been cleaning it with a dry lint free cloth.
I've noticed though that lots of people online recommend that you clean them with isopropyl alcohol, yet the instructions from Brother specifically forbid the use of alcohol (and for that matter any liquids in general).
Are the people at Brother being overly cautious? Or can the use of isopropyl alcohol on the photosensitive drum really cause damage? And if so what sort of damage can it cause?
