Talking towels... I had a bunch of nice MFT 600's that have used for over a year to do rinseless. Over time they became rather water resistant despite washing promptly after each use with formerly CG microfiber wash and now the Wolfgang product. There was an earlier post about "resetting" towels.
"The Boiling Method (212 F)
Boiling water breaks down the build up of chemicals, wax, sealants, cleaning products in the fiber.
Korean manufacturers have recommended the use of “boiling” microfibers to ensure any of the dyes or contaminants from the factory are fully gone.
Be careful of boiling timetables, limit up to 20 minutes. May fade dyes."
Since the towels were "water resistant" to the point of floating for about 30 seconds when dropped into a bucket of rinseless, I thought well, why not? I put about a gallon of hot water from the tap and then several large pot-fulls of boiling water with a couple oz of Optimum Opt-clean and put a half dozen towels in the mix and agitated them a couple of times over about a half hour period. I rinsed them by wringing them out and dunking them several times in another bucket that I ran a constant stream of water into under the faucet in the bathtub. Then they went into the washer with a small amount of WG Microfiber Cleaner and restorer.
I was a bit worried about exposing MF to near boiling heat, but the towels had gotten to the point that I was considering replacing them all anyway.
The result? Wow, the towels came out super soft and sank like a stone when dropped into rinseless bucket. Totally useable again. Not sure how this will affect the longevity of the towels, but for this batch it saved them from the trash bin. Will try it again in a few months with these towels and see how they do. Have to say I was really surprised with the result of this. Props to the OP on the microfiber care thread who suggested this.
PS- to the MFT vs Eagle posts above, Tony sent me a grey MFT unit and I really like it as compared to the Eagles. The grey actually felt softer, and they are about a dollar cheaper. Shipping prices will offset this a little depending on where you live, but I am going to go with MFT for this towel. I ordered some myself before I got the unit from Tony, and received the blue silk bordered ones instead of the edgeless I ordered, and I swear the blue feels different from the edgeless grey. It feels lighter and slightly thinner. Tony seems to think I am nuts on this, as MFT contends they are the same, but they just feel a little different to me. This may be isolated to a single batch, but I am going to be ordering the edgeless greys going forward.
