I purchased some 3D Towel Clean and although I'm no pro detailer... I do know how MF towels feel when NOT cared for, lol. Anyway, I had ordered some new MF towels to replace my junk Wal-Mart ones.
So, I went ahead and did a pre-cleaning rinse with straight water and vinegar to clean out our top-loading, old school, agitator washing machine.
(I did this just to be on the safe side... besides, I make my own laundry detergent out of Borax, A&H Laundry Booster, A&H Baking Soda, Oxyclean, & some grated up Fells-Naptha, so I don't think there would be any accumulated amount of 'soap' as we only use 2 tablespoons per load and it doesn't "sud." Again, just playing it safe.)
Anyway, and to the point- After the pre-cleaning-rinse of the machine, I did my old, nasty, stained, heavily-linted, MF, Wal-Mart rags with a cap full or two of (clueless on how many ounces this ended up being) on a medium water setting. Then dried them on low heat in the dryer.
BAM! No lint, old stains mostly gone, and the feeling of them was amazing! Couldn't believe the difference in the Wal-Mart rags! At least I can keep them to do some wheel or window cleaning.
The 2nd load with my new 'better' MF towels (washed them just to be sure they were clean) were just as soft and 'fluffy' as when I pulled 'em out of the pkg.
Nice job 3D! I told my wife..."Hey, that green liquid stuff... stay out of it! And don't touch THESE towels...EVER!" (pointing to my new MFs)
Note: I don't have anything to compare Towel Clean to, as I have just used only it as a dedicated MF detergent. Well, I can compare it to Tide I used quite a few years ago before making my own detergent and it is WORLDS BETTER than Tide.
