- 3Microfiber or chenille mitts hold suds and release dirt in the rinse bucket. Replace dropped mitts or rinse them thoroughly.
- 4Large — plush microfiber towels absorb water without dragging. Blot or pull gently instead of scrubbing.
- 5pH-neutral car soap protects wax and coatings. Wash in shade so soap doesn't dry on the paint.
