What do you do with your microfiber towels after they have been used? Do you wash them and re-use them again on painted surfaces or do you wash them and turn them into shop towels? I have thought that washing them in the laundry won’t get out all of the wax or whatever else you previously used them for. A paint friend of mine said they are so cheap now that he doesn’t re-use them, but I have some that are big, plush, and my inner-frugalness is having trouble turning them into shop rags 
I wash and re-use them but have been told (and I adhere to this) to avoid drying them with fabric softener sheets.
Hadn’t heard the softener sheets thing, doesn’t seem to be hurting my towels, but maybe the softener chems do funny things to paint???
My biggest problem with them is they collect pieces of _________ (grass, metal, etc), and then become useless for wax/wash work. When they hit that point, shop rags they become.
I have either heard not to use fabric softeners or not dry them at all. Mine get fuzzy after washing and drying them.

I never found them to be as good after a wash or two compared to when new. I will usually use turn them into shop rags after they get too dirty.
I have a pile of them that my girlfriend washed. The problem is I’m not sure if and what ones she put in the dryer with other clothes and fabric softener. Do you think running them through the wash again will take out any fabric softener that might be in them?
Good point Diesel D, they don’t seem to be quite as soft after they go through the laundry do they.
I have a set of nice microfiber towels that I only use for wash/detail/waxing. I wash them in the washing machine by themselves, with a small amount of detergent on cold water. Then I run them in the dryer for 4 minutes on air only-no heat setting. Do not use a dryer sheet and make sure lint trap is clean. Afterwards hang them up to finish drying. It’s a tedious process but it makes them last.
The dryer sheets will remove the electric charge from microfiber towels that make them so effective at grabbing dirt. Too much heat will start to melt and curl the fibers making the towel pretty much useless.
The good set of MF towels I have is only for touching paint, never on wheels/underhood/etc. I buy the cheap towels for that and/or use worn out good ones.
