How OCD are you about MF towels?

Da Fuq?

I just use blue shop towels, after I'm done I just throw them away.

 

lol!!

 

I own hundreds, if not thousands of the blue and yellow 3M microfibers, as well as cheaper microfibers.

My setup has been this for the last five years:
Costco fibers for glass have their own bins
Costco fibers for general cleaning have their own bins
Other fibers are considered junk and used for almost anything, they have their own bins
3M Blue microfibers are used with final polishes and glazes only
3M Yellow microfibers are used with compounds, polishes, and waxes. Bins for each type of material.

As for drying, I dry with air only.
