A charity car wash in Chorley raised almost £500 for Help for Heroes.
The event, at the Hop Pocket pub car park in Carr Lane, was organised by mum-of-three Jacci Jones.
Her son, Karl Jones, is an aircraft technician in The Royal Electrical and Mechanical Engineers (REME), while Michelle is training to be a dental nurse in the RAF.
She said: “The car wash was a great success. We raised about £250 on the day and with the sale of wrist bands and car stickers we should break the £500 mark.”
The car wash was completed by Karl, 23, his sister Michelle, 21, and fellow servicemen.
Jacci said that the public’s support, and that of ex-servicemen who attended, gave the servicemen a real boost.
She said: “All the boys said how good it is that they feel really supported in the job they do by the general public’s kind words and thoughts.”
Karl will be leaving for Afghanistan in two weeks’ time.
