Car wash recommendations

Anyone got any local car wash recommendations? It can be hand wash, mechanical or jet wash - I just need to get the sand, seasalt and mud off after a weekend of camping before the car starts rusting! (Although saying that, I've not been through a mechanical one for years so it would be exciting if there is a local one)

I saw there were a few threads on here but all of them were quite old and I don't want to contribute to the traffic in the borough by driving around looking for one that's closed down.
