Manually Cleaning ETB Color LaserJet 4700

[jloader1]

Any recommendations on manually cleaning the ETB in a Color LJ4700? I have toner particles remaining on the roll. I have yet to receive a "Replace Transfer Kit" message. Although, I think I know where this is going to end up. Any advice would be welcome.

I don't know what the rules are, but I personally wipe down the ETBs with a soft cloth and sometimes used a can of air to blow out the gears. I haven't damaged one yet.
