I don't get lint on mine, because don't wash them in the washer. I just soak them in a basin of soap and water for a while, then give them a rinse and hang them up.

If you do them in the washer don't wash them with towels or stuff that is linty.

I wash my microfiber cloths separately from other items. I have about 30 of them, and I collect the dirty ones in a bucket until I have enough for a small load. Still, I get sawdust and lint on them occasionally and then have to hand pick that stuff off.

Maybe you don't need to worry too much about removing the lint. After all, you've cleaned it and if it's sticking to the cloths it won't be redeposited on what you are cleaning.

I do wash my microfibers alone never with other clothes. I keep a large zip lock bag with my cleaning supplies and put the used ones in that until I have enough of them for a small load.

I wash mine separately in the washer and dry them in the dryer. If needed, I pick off by hand some lint afterward. Sawdust is the worst: I learned never to use them for house construction projects. I also buy only the relatively inexpensive cloths from a place like Target or Walmart (in automotive; they come in stacks of 6 or 8) and don't feel too bad when one needs to get tossed.

Rather than picking little pieces off, one at a time with my fingers, I use a lint roller, the kind with sticky, perforated squares that you tear off. Amazing how much imperceptible lint is hiding in your microfiber towels! You’d never get it off by hand because you wouldn’t know it was there in the first place. Try a lint roller and see what you think.

I just put mine in the dryer with non-linty items and they are never linty when they come out.
