I cleaned out the existing cartidges in the 600 I got. I drilled holes
in the tops (had to anyway to refill) and used a vacuum to pull
cleaning solution through the foam. A nebulizer from the thrift store
pulls hard enough, although it was built for pressure rather than vacuum.

It takes a moderate amount if the cartridge is already mostly used up.
Then I pull just air through it for a while to get most of the water
out. Don't try and dry it out, that's not good anyway and a tiny bit
of water in there won't dilute the ink much.
