Hot-Water Concrete Cleaning for Driveways, Sidewalks & Commercial Surfaces
Oil stains, algae, tire marks, and years of embedded grime — our hot-water system removes what cold-water washing leaves behind.
Why Hot Water Makes All the Difference on Concrete
Cold-water pressure washing moves surface dirt around. Hot water breaks the molecular bond between contaminants and concrete — dissolving oil, grease, algae, and embedded grime that cold water simply can't touch.
Therm-O-Jet's signature hot-water system has been the difference-maker for NJ homeowners and commercial property managers since 1981. Whether it's a residential driveway, a commercial parking lot, or a loading dock caked with grease, we deliver results that last.
Our self-contained trucks carry their own water supply — no hookup to your property required. We show up, clean, and leave the surface looking like new.

Concrete Cleaning FAQs
Can you remove oil stains from concrete driveways?
Yes. Hot-water pressure washing combined with appropriate degreasers is highly effective at lifting oil, grease, and automotive fluid stains from concrete. Fresh stains respond best, but our hot-water system can significantly improve the appearance of older, set-in stains as well.
How often should concrete surfaces be professionally cleaned?
For residential driveways and patios, once every 1–2 years is typical. Commercial surfaces like parking lots, loading docks, and sidewalks benefit from more frequent cleaning — quarterly or semi-annually — to maintain appearance, prevent slip hazards, and comply with municipal codes.
Will pressure washing damage my concrete?
Not when done correctly. Our technicians use the appropriate pressure and nozzle distance for each surface type. Older or damaged concrete may require a lower-pressure approach. We assess every surface before starting to ensure we clean effectively without causing harm.
Do you clean commercial parking lots and loading docks?
Yes. Commercial concrete cleaning is a core part of our business. We clean parking lots, loading docks, warehouse floors, sidewalks, and any other concrete surface for property managers, businesses, and municipalities throughout northern New Jersey.
Do you need access to our water supply?
No. Therm-O-Jet operates fully self-contained trucks with their own water tanks and heating systems. We never need to connect to your property's water supply, which means no disruption to your operations.
