There are many different grades of micro fiber to choose from. From the expensive to the inferior. In the case of wax removal, just because it was expensive didn't mean it was the best either! The non-abrasive, wedge shaped micro fibers lift and hold onto wax better than cotton and are lint-free. Plus these cloths, when washed (without bleach), don't hold onto wax and other stains over a period of time. Set includes three 16" x 16" cloths, color coded so you only use them for wax or sealant removal.
