Professional auto detailers or car enthusiasts love to use this nanoskin auto scrub wash mitt because they can simply slide their hand inside and start to decontaminant cars. The size of this mitt is 6" x 8.7". The area that contact with the car is much bigger than traditional clay bar which allows you work more efficiently. The rubber polymer coating removes paint over spray, bugs, road tar, rail dust and industrial fall out which you can NOT clean by washing. Always "clay" the above surface before applying wax or polish. This nanoskin auto scrub wash mitt can help you remove the contaminations on the clear coat finishes and achieve the squeaky clean result. Fine grade is ideal for well maintained vehicles.
