Coffee on drums - how to clean this?
 

Hi,

I got a big HP printer (with the optional duplex printing hardware
already installed) for free because the previous owner managed to
pour lots of coffee over and into it and decide to better go and get
a new one. The printer itself still works and just needs a simple
cleaning. cleaning job.

But the drums of the cartridge are coffee-stained, too. So I'd like
to know is there a way to clean the drums in a way that would make
the stained parts pick up toner again?

Thanks,
Carsten
