It's fine to machine dry your MF towels, provided you clean the lint filter in your drier, you don't wash/dry MF towels with anything but other MF materials, and you aren't a household that uses fabric softener sheets (that stuff contaminates the inside of the drier).
thats what i do as well if there still somewhat clean I'll use them for rims or for door jams
