Restaurant Pressure Washing
in Pomona, CA

LA County Environmental Health expects exterior food facility surfaces to be maintained clean on an ongoing basis, and the LA County Stormwater Program reinforces quarterly service as the standard interval. High-volume operations — birria specialists, carnitas houses, and catering kitchens with active loading docks — should consider monthly or bi-monthly service during summer when grease breaks down faster in Pomona's heat.

No. LA County Municipal Code §12.80 explicitly prohibits discharging wash water containing grease, detergents, or food waste into storm drains. Boh's vendors use containment and proper disposal methods for all wash water, and provide written confirmation that the service was performed in compliance with §12.80.

Loading docks, dumpster enclosures, grease disposal areas, and any back-of-house exterior surfaces where grease or food waste accumulates are the primary targets under LA County Environmental Health's exterior cleanliness standards. Operators on Garey Avenue and in the Downtown Arts Colony often add sidewalk-adjacent surfaces to their scope.

Yes. LA County Environmental Health cites exterior grease accumulation under general facility cleanliness, and it contributes to overall scoring. A heavily grease-coated loading dock or dumpster area can push an otherwise clean inspection into citation territory, particularly if it is near food receiving areas.

Pomona sits in the Pomona Valley and regularly sees higher summer temperatures than coastal or mid-LA cities. Heat accelerates FOG breakdown, which means grease liquefies, spreads faster, and penetrates concrete surfaces more quickly. Operators who wash quarterly during cooler months often need to add a summer service to stay ahead of odor, pest pressure, and stormwater compliance.

Decomposing grease and food waste in dumpster enclosures and loading dock drains creates harborage conditions for cockroaches. Pomona's older downtown building stock — particularly the commercial buildings on and off Garey Avenue — already provides structural harborage; standing grease makes the problem significantly harder to control with pest treatments alone.

They address the same problem at different points. Grease trap service captures FOG before it enters the sewer system; pressure washing removes what accumulates on exterior surfaces before it reaches storm drains. In Pomona's summer heat, both services often need more frequent scheduling than operators initially expect.

Clear access to loading dock doors, dumpster enclosures, and back-of-house areas. Confirm your water access point with the vendor in advance. If your restaurant is in a shared building — common in the restored commercial blocks of the Downtown Arts Colony — coordinate with your landlord on any drainage or containment requirements beforehand.
