Retail built West Covina, and most of it faces the 10. Two regional shopping centers, a long row of auto dealerships on the freeway frontage and dozens of restaurant pads sit within a mile of the ramps, which adds up to a great deal of parking lot. Parking lots are what we do most outside of gas stations. Pressurize Washing Systems is about twenty minutes away in Chino, and we wash large lots, sidewalks, drive-thru lanes and dumpster enclosures overnight with hot water and wide surface cleaners that cover ground fast. Wash water is recovered on site. Our crew of five is licensed and insured, holds a 5.0 rating on Google, and offers a free demo, so a center manager can compare a cleaned strip of sidewalk with the rest.
Commercial properties we clean in West Covina
Regional and power shopping centers, auto dealerships, chain restaurants and drive-thrus, medical offices, a hospital district, banks and neighborhood strip centers. The steady needs are parking lot and parking structure washing, sidewalk cleaning with gum removal, drive-thru and dumpster pad degreasing and storefront washing. Dealers want display lots and service lanes cleaned before opening. We also handle commercial windows, hard water stain removal, graffiti removal and common-area cleaning for HOA and multi-unit properties in the hills.
What West Covina does to concrete and buildings
The east San Gabriel Valley is hot from June into October, and asphalt and concrete lots here soak up oil that the heat then sets hard. Smog and freeway soot from the 10 settle on storefronts and signs facing the frontage roads. Santa Ana winds bring dust and palm debris in fall. On the south side, the San Jose Hills shed silt onto lots after heavy rain. Hard water from landscape sprinklers leaves white scale on curbs, monument signs and glass, and gum and drink spills collect wherever shoppers wait, at entries, food courts and bus stops.
Where the wash water goes
Storm drains here flow to Walnut Creek, a concrete channel that crosses the city and joins the San Gabriel River. We block inlets and recover wash water before it can get there.

Our specialty
Gas station cleaning in West Covina
Stations here crowd the 10 ramps at Vincent, Azusa, Citrus and Barranca, and continue south along Azusa Avenue, Sunset Avenue and out to Amar Road. Mall shoppers and freeway commuters keep the pumps turning all day, and valley heat bakes drips into the pads through the summer. We are close enough to keep a station on a monthly cycle without trouble. Each visit covers the fuel islands, pads, dispensers, canopy, columns, trash areas and the walk in front of the store, using hot water and degreaser, with wash water vacuumed up instead of sent to the gutter.
We maintain more than 200 stations across California. Fuel islands, canopies, forecourts and store fronts are washed overnight with hot water, one island at a time, and the wash water is recovered.

What our commercial customers say
These guys came out and did a great job for my commercial flooring business. Place looks brand new again.
tyler m. Google review · Commercial business Pressurize Washing Systems knocked it out of the park. They did an outstanding job power washing and deep cleaning our gas stations and car washes—canopies, store exterior, windows, floors, even stubborn gum that’s usually impossible to get rid of. The sites looked noticeably brighter and more professional the same day. They showed up on time, worked efficiently, and clearly know what they’re doing. If you care about curb appeal, brand standards, and keeping your properties looking top-tier, these guys are a no-brainer. Highly recommend.
Arian Z. Google review · Gas stations & car washes I recently had my gas station pressure washed by Pressurize Washing Systems, and I couldn’t be happier with the results. Their communication was excellent from start to finish, and they were very accommodating with my schedule, which made the whole process seamless. The attention to detail really stood out they didn’t miss a thing, and the station looks incredibly clean and refreshed. You can tell they take pride in their work. Overall, great service and a great experience. I will definitely be using them again and highly recommend them to anyone looking for reliable, high quality pressure washing.

West Covina FAQs
Commercial pressure washing in West Covina: your questions
Can you wash a full shopping center lot in one night?
It depends on size and how dirty it is. With five people and wide surface cleaners we cover a lot of ground, and we have washed a 260,800 square foot parking lot in Santa Ana. Large centers here are usually phased over several nights so stores and overnight deliveries are not blocked.
How close are you to West Covina?
About 17 miles. From our yard in Chino it is roughly 20 minutes off-peak, north on the 71 and west on the 10, or west on the 60 and up Azusa Avenue for the south side. That makes same-week site visits and free demos easy to arrange.
Do you clean drive-thru lanes and dumpster enclosures for restaurants?
Yes. Drive-thru lanes collect oil, coolant and spilled drinks in the same few car lengths, and dumpster enclosures collect grease. We hit both with hot water and degreaser after closing, rinse the menu board and curbs, and recover the water. Most restaurant pads here do well on a monthly schedule.
Are you licensed and insured?
Yes. Pressurize Washing Systems LLC holds California contractor license CSLB #1152154 and is insured. We send a certificate of insurance to your property manager or brand on request.
What is the free on-site demo?
Before you commit, we come out and wash a test patch on your worst concrete. You see exactly what our hot water equipment does on your surface, and we see what the job needs. It costs nothing and there is no obligation.
