- "Thank the maker! This oil bath is going to feel so good. I've got such a bad case of dust contamination, I can barely move!"
During the Clone Wars, Droid Spa, a maintenance spa business on Coruscant, offered an automated oil bath as part of their regular service. During the Age of the Empire, the Jelucani teenager Thane Kyrell managed to bribe his tutor droid CZ-1 into releasing him from his mathematics lesson by offering him a lubrication bath.
After traveling through the desert of Tatooine and being captured by Jawa scavengers, the protocol droid C-3PO was purchased by Owen Lars, who turned the droid over to the care of Luke Skywalker. Skywalker, noticing the heavy dust contamination on C-3PO, gave him an oil bath, which delighted him.
