The name Drywasher refers to cleaning without a conventional rinse. The dirt is not literally wiped away dry, which would create a high risk of scratching.

A waterless-wash product uses lubricants and cleaning agents to surround light dust and reduce friction as it is lifted from the surface. Older explanations sometimes describe this as a magnetic effect; in practice, lubrication, surfactants and safe wiping technique are what matter.

Apply enough product to wet the small section being treated and allow it to soften the contamination. Use several clean, plush microfibre towels rather than carrying dirt around the complete vehicle with one cloth.

Wipe gently in controlled lines, turn the towel frequently and stop as soon as a clean section is no longer available. A separate towel can then be used for the final finish.

A waterless wash cleans and may leave a light protective finish, but it does not replace paint correction. It should not be described as polishing unless the product genuinely contains abrasives and is used through a polishing process.

Heavy mud, road salt, sand, bonded contamination or an unknown gritty film requires a proper rinse and wash. Using a waterless product beyond its limits can mark the paint regardless of its quality.

AVP recommends beginning with a thorough professional clean and then using waterless maintenance only for suitable light contamination between full washes.
