A wash kit is the foundation of any detailing routine. You need a shampoo that foams but doesn't strip protection, a mitt that picks up dirt without scratching, and a drying towel that doesn't drag or smear the paint. That sounds simple, but quality differences are significant.

A good wash kit also includes the right bucket, ideally with a dirt-trapping grit guard at the bottom. That guard keeps coarse dirt out of your mitt and off your paint. When choosing, check that everything works together in terms of volume and intended use.
