Saturday’s charity car washes at three fire stations in Milton Keynes raised a total of £1,915.
The events were held at Bletchley (£460), Broughton (£950) and Great Holm (£505) from 10am to 2pm.
Firefighters at Marlow, where a domestic hosepipe ban has already come into force, put their buckets to good use by raising £540 with a street collection.
Crew Manager Dave James from Marlow Fire Station said: “As we cannot currently do car washes this was another way to raise funds, and we had a great reaction from the public.”
The money at all four events was being collected for The Fire Fighters Charity, which provides support and assistance to serving and retired fire and rescue service staff and their families.
Station Manager Keith Williams, Buckinghamshire Fire & Rescue Service’s charity coordinator, said: “I would like to thank everyone who organised and supported these events as the money they raise makes a real difference to our charity.”
