 It will remove all the wax residue, any of the grease or grime that you have in your towels, bring them all back to life. And if you have some really dirty towels, you put two or three capfuls in a bucket of water, soak your towels overnight, and then wash them in the machine. And it comes, again, in another 16-ounce bottle, and it is $16. So I have not tried that yet, but probably will when I need some. But I'm a big proponent of using the microfiber detergent for your towels.
