How often do you wash your rig when camping on the beach

We camp often on the beach in California. I wash the RV when we get back home before it goes back to storage. A good wax job holds up well to the salt air.

Touch-up any chips or nicks in painted areas to keep rust from grabbing hold.

Our RV is 20 years old and has spent it's life at the beach or within 6 miles of the ocean. It still looks new.
