Thanks for this thread. I've been wondering if what I'm doing is really the best, and you guys have given me some great ideas.
For background, I've been washing in a seperate load, using Tide's liquid detergent that doesn't have perfume, softeners, or coloring. Doube rinse cycle, then air dry on a rack. In FL humidity, that can take a while
Lately I've been adding Oxyclean in hopes of salvaging a few more smudge-stained MF towels. I'm not sure it's working. Being the paranoid sort that I am, I pre-disolve the powder in a glass of hot water to make sure I don't end up with undisolved oxyclean granuals trapped in my MF towels, but the Oxyclean seems to be outgassing a lot as I stir it up, so I'm probably not getting an effective dose.
Some comments/questions:

Maybe I can help explain why Micro-Restore is better than other detergents for cleaning microfiber than other detergents.
1. It is a very strong degreaser. If you notice when you get it on your hands, it really dries them out. In fact, the formula is a modification of a garage floor degreaser, and a wheel cleaner (removal of break dust).
OK, not to be confrontational, but you do know that brake dust isn't greasy? It's a PITA to get out of MF - as bad as getting it off the wheel, but not because it's greasy. If it were greasy, it would make a lousy brake material. It's just a fine particle that's ideal for MF to latch onto. What's needed is to somehow "relax" the MF so it releases the particles. But that's only brake dust. I think grease (the black crud that seems to collect on the bottom edge of your body, and the bottom of doors) is what kills more MF towels prematurely.
This means that it is better at removing all of the tough oils, and grease that you get on your towels when cleaning a car. It is also well suited for removing wax and polish residue from your microfiber products.
So basically, then, any good degreaser is good. As long as it doesn't foam up and out of my washer, that is. Then I may be looking for a better degreaser than laundry detergent. So "Simple Green" or Castrol's purple A/P cleaner/degreaser ought to be good? Or Greased Lightening's "Orange Blast" A/P cleaner/degrease? "Orange Blast" degrease does a dynamite job on brake dust. I like it better than "Orange Blast wheel cleaner."
2. The formula contains water softeners. Have you ever noticed that over time some of your towels seem to stiffen (especially some waffle-weaves), or become less absorbent? I have found that this is often caused by washing in hard water (water that contains high levels of calcium and magnesium). Just like fabric softeners, the calcium and magnesium minerals can clog the tiny pours in microfiber towels, making them more stiff and less absorbent. Micro-Restore makes sure these minerals are not left behind. Other detergents do not.

I'd describe local water supply as moderately hard, so this peaks my interest. The "red flag" that goes up in my mind, however, is that you're carrying through chemicals from the wash through the rinse cycles to treat the water. That doesn't sound good to me. I'd think you'd want a detergent that did everything possible to get the heck out of my MF towels, and not risk becomming a contaminant.
I can see adding vinegar to my rinse water. It'll tend to neutralize soaps if they're present (usually slightly caustic, but there's a difference between soaps and detergents), and it'll keep the minerals in the water disolved. It'll also evaporate easily, and as a side benefit, disinfects.
So if I'm worried about hard water during the wash cycle (since I'll now be using vinegar in the rinse), why not something like washing soda (Borax or Calgon)?
You might have a great product, but frankly, OTC stuff I can buy at the grocery store is a LOT more convenient. Unless your product can actually help me salvage some of those grungy MF towels we all seem to end up with sooner than we want, the convenience factor combined with shipping expenses dictate OTC solutions for me.
Thanks,
