How does Guatay's climate affect this service?

Guatay is tiny mountain community at 3,500 ft elevation on SR-79 between Julian and I-8. Gateway to Cuyamaca Rancho State Park, cabin and small-home stock, off-grid-capable battery configurations standard. Quarterly cleaning during snow-free months is the working baseline.. A good pro accounts for local conditions on every job.

Is it really a stain or just dirt?

Regular cleaning makes it cleaner but the etching remains. The test: clean the panel with DI water and look at it backlit. If there's still a haze or rainbow shimmer, that's etching.

Won't acid damage my panels?

Concentrated acid would. The pro uses a dilute, panel-safe formulation that works in the 2-5 minute contact range, then a full DI rinse to neutralize. Manufacturers test panels against this method during certification.
