I separate my towels into 3 categories:
- Terry cloth
- MF for paint
- MF for wheels, underbody
I never, ever co-mingle any of the above when washing. The terry cotton occasionally will shed lint which will get trapped into the MF fibers. So the terry's get their separate treatment; hot wash, liquid detergent, mixed with simple green - no bleach or fabric softener. I throw those in the dryer.
The MF's used for paint - warm/cold wash, liquid detergent, SG & distilled vinegar. I just air dry them. I don't want my MF's in the dryer due to the potential of picking up lint from the dryer.
The MF's for underbody and wheels - I always presoak in a bucket of SG prior to washing. Those towels typically need an extra dose of SG for the degreasing affect. I let it presoak for at least 1/2 day. After pre-soak, I wash them like my MF paints above. Air dry as well.
On another note I like to batch up my washes so I have special containers to hold towels prior to washing. Prior to washing, I store the dirty MF's in separate containers for MF paint towels and underbody(with lids - to eliminate any dirt falling into the container) so that further cross contamination is eliminated. The main reason is I want my MF's for paint to last as long as possible and without fear of having any grit inside those fibers. It's anal, but I just want to do anything it takes to eliminate any kind of swirls coming from my towels - either from bad wiping techniques or, cross contamination.
On a final note, I store each towel (terry, MF paint, MF underbody) in their separate plastic baggie. The terry cloth require larger zip lock bags - Hefty makes a 10 gallon bag so I store like 3 towels in there. Squeeze out the air, and store them on the shelve ready for the next wash.
For the MF's, I just use regular hefty 1 gallon zip lock bags with the pulls. I keep the MF paint towels separated as well as the underbody. I mark the underbody bags with a sharpie pen on the outside label.
Now you will know I am full on nuts. I separate my good MF paints - WW's are in a separate bag, QD towels separate, Polish MF's separate, etc. I take all those bags and store them in a clear plastic container. So when I wash, I get my chemicals, grit guard bucket, mitts and pull out my clear plastic containers with WW's and Terry's. I can do it blind, because I know I store my containers in the same place.
I am starting to ramble, but I do the same procedure for my buffing pads. Each pad get a baggie and stored in a plastic container. So that when a buffing day comes along, I pull out the PC, the container with buffing pads, container with the buffing chemicals and the MF towel container.
And then there are the brushes...never mind you get my point. I am a sick person...
