“This is a product worth purchasing. I've tried various non bio detergents to wash clean my cloths. However, these invariably work best with a conditioner as we live in a hard water area - something that must not be used with microfiber cloths. I've found that the Nanolex wash keeps my cloths in tip top condition. Use on a 20-30 degree wash, fast spin and then air dry the cloths. Store in a dust free container.”
