How often should you wash your car in San Diego?
It depends on what lands on your car and how much you want the paint protected. Here is a simple way to decide.
What sitting dirt does
Bird droppings, tree sap and road film left on the car eat into the clear coat over time. Near the coast, salt air dulls paint and spots glass. Under trees, sap and pollen bake onto the paint, and sprinklers leave hard water spots behind. The longer it sits, the harder it is to get off.

A simple rule
- Want the paint protected: wash weekly. The Gold wash adds Simoniz hot wax every visit, so weekly washes keep it topped up.
- Something landed on the paint: wash it off soon. Light sap that has bonded comes off with a clay and wax, $160 for a car.
- Light dust only: a Bronze wash for $13, hand dried, with free vacuums.
When unlimited pays off
If you wash twice a month or more, an unlimited plan costs less than paying each time. Bronze is $19.99 a month on sale and a single Bronze wash is $13, so it pays for itself by wash two. At eight washes a month, Gold works out to $5.00 a wash instead of $21. No contract, cancel anytime.
Questions
Not with a gentle wash. Our tunnel uses soft cloth and mild cleaners, never acids or harsh brushes, and every car is dried by hand.
If you wash twice a month or more, yes. The Bronze plan is $19.99 a month on sale and a single Bronze wash is $13.
A clay and wax ($160 for a car) lifts light sap and bonded grit. Heavy sap, water spots, overspray and road tar get a dedicated treatment from $250.
