Sonic cleanser

The Sonic Cleanser is a Terran device primarily found on capital ships such as the Battlecruiser. Similar to jets that blast the meat off bones at slaughterhouses, it consists of a high pressure water jet that washes the user as efficently and in as short a time as possible, a blast of hot air drying him/her imidiatly afterwards. In some cases, the ship's commanding officer has access to less intense cleaning, posessing a regular shower with 'real' water (albiet for only thirty seconds, as per regulations).

The Sonic Cleanser is also used at isolated research stations where water is in short supply.
