How does San Ysidro's climate affect this service?
San Ysidro is the southernmost residential zone in our service area, at the Mexico border. Dense urban housing stock, Otay Mesa industrial dust drift from the east, and Las Americas outlet mall commercial solar. Quarterly cleaning is the working baseline because of the layered dust film that does not rinse in rain.. 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.
