Put lots of washing powder/liquid in and rollers come out nice and clean.
Not seen any contamination of washing machine yet, though I sometime run
it
again empty (with a tad of powder/liquid) just in case.


For oil based paints, perhaps someone could try connecting the washing
machine's cold water hose to a big drum of white spirit, and let us know if
that works too?
