What do Mission Valley homeowners ask about soft wash?
How fast can you get to Mission Valley for soft wash?

What does soft wash cost in Mission Valley?

How does Mission Valley's climate affect this service?
Mission Valley solar cleaning is heavily commercial, Fashion Valley, Westfield, Hotel Circle, and the Friars Road condo corridor dominate the call mix. I-8 corridor heat-island effect plus traffic film from the surrounding freeways drive heavier soiling than typical central San Diego.. A good pro accounts for local conditions on every job.
How is soft wash different from regular pressure washing?
Pressure washing is 1,500 to 4,000 psi water blast. Soft wash is under 60 psi with a brush doing most of the work. Pressure washing can crack the anti-reflective coating, force water past the panel seal into the junction box, and void warranties. Soft wash is the only method most manufacturers explicitly permit.
Why deionized water?
DI water has zero dissolved solids. As it dries on the glass it leaves no mineral spots. Tap water in San Diego is hard, it dries to a calcium film that bonds to glass and reduces transmission permanently. The pro carries a truck-mounted DI tank and check ppm before every job.
