That marine layer rolling in off The Cove every evening? It’s depositing microscopic salt particles on your paint while you sleep.
By morning, the fog burns off – but the salt stays. Worse, salt is hygroscopic: it pulls moisture from the air even on sunny days, creating a corrosive film that never stops working against your finish.
If you’ve parked near Children’s Pool or anywhere along Coast Boulevard, you’ve noticed your windows get hazy faster than they should. Dark paint shows dullness within weeks. That’s not your imagination – it’s La Jolla’s coastal chemistry at work.
The Silent Cycle
- Night: Marine layer deposits salt on your car
- Morning: Fog burns off, water evaporates, salt stays
- All Day: Salt pulls moisture, creating a corrosive film
- Repeat: 365 days a year in La Jolla
