Charity car washes are being held at Abingdon and Bicester Fire Stations this weekend.
The events, supporting The Firefighters Charity, will take place at Abingdon from 9am to 1pm, and at Bicester from 9am to noon, both on Saturday, March 16.
The charity supports current and retired firefighters with their physical and mental health, and social needs.
Abingdon Fire Station, on Ock Street, said they will have vehicles "shiny in no time".
The team will be accepting donations by cash or card.
They encouraged locals to "bring us your dirtiest vehicles" and "help us raise money for a really good cause".
Additional car washes at other stations will also be scheduled soon.
The forecast predicts a dry day.
