I just handwash them myself in a 5 gallon bucket. I like washing them right away, especially dirty ones, and I usually don't have enough to put in the washing machine. Use cg microfiber wash since it was on sale and I wanted to give it a try. It works very well, I like how it rinses out very easily. I usually wash paint/qd in one batch, interior in another, dirty "rag" ones on separate wash, with apc (poorboys, 1z, and optimum) have all worked well. You can probably go with interior/paint together, it's just the mf towels I have for paint are nicer so I just like separated :chuckle:
