Waterless and rinseless products use lubrication to lift light contamination into clean microfibre rather than dragging it across paint.

They are appropriate only within the product instructions. Mud, road salt and grit-heavy surfaces should be pre-rinsed or washed conventionally.

Use several clean towels, turn to a fresh face frequently and stop when contamination exceeds the method's safe limit.

The Rubin One Drywasher described in the archive was one such product; the “best available” claim is not independently established and current availability should be confirmed.
