I have 2 each of the big and small ones. Like all MF towels, keep them in storage bins or plastic baggies away from dust and dirt when not in use. Use them dry from their storage. When I do a regular wash, I sheet the water during rinse so the big guzzler barely gets wet even on a mini-van. When I do an ONR wash on my van, I have to wring it out once before I'm done. With an ONR wash on my smaller hatchback, it holds up well till the end.
