Even after a thorough car wash, there are times when you still need to wipe down areas where grease, dirt and grime hide... and you don't want to contaminate and stain your nice Micro Fiber towel or chamois. For those areas such as door-jambs, seams, engine bays, trunk and engine gutter rails and wheels with left-over brake dust, I use these ultra-soft, premium grade, non-woven Micro Fiber towels. Perfect anywhere you need a quick touch up. Did I mention they work great as a window wipe down towel, too? Set includes twelve 13" x 13" towels that are machine washable! Cheap enough to be disposable, strong enough to use over and over! Keep them handy in the car for accidental spills, or keeping your windows streak-free. These are a favorite of mine.
