I want to wash my microfiber towels that I purchased from autogeek. I plan on using the Pinnacle Natural Brilliance Micro Rejuvenator that I got as well. Am I supposed to add regular laundry detergent along with the rejuvenator? All it says on the bottle is to add to your wash. It says for heavily soiled items, to add 1oz. to a 5 bucket gallon of water and let soak.

Also, I really don't want to dry them in the dryer because I'm afraid it will pick up any minute particles of dirt that may have come off the clothes, or managed to get in there some other way. Can I just air dry them?

I wash all of my rags, MF, cotton, whatever, in their own load with normal detergent. However, I usually air dry them, and never use dryer sheets if I do end up using a dryer. Some people even machine wash their chamois with their laundry.

You should use just the pinnacle... Then hang dry the towels.

Use no powdered detergent nor fabric softner.
