Check for cracks, flaking, old sealer and low spots before wetting the slab. Gather a stiff nylon broom, a concrete-safe cleaner, garden hose and eye protection. Avoid wire brushes and unlabelled acids.

Work in manageable passes
Move vehicles, sweep loose grit and pre-wet nearby plants. Test cleaner on a small area, follow its label, then work from the high side toward a safe drain. Keep each pass overlapping and rinse before the solution dries.
Protect the slab and the runoff
Do not hold a narrow pressure tip close to the surface; it can leave wand marks or expose aggregate. Keep wash water and chemicals out of storm drains where local rules prohibit discharge. For oil, rust or old sealer, identify the stain before choosing treatment.
South Jordan field note
Irrigation overspray and tracked winter residue are common reasons homeowners inspect concrete in the Salt Lake Valley. Check the driveway again after snow season and before sealing; the slab must be clean and fully dry first. Epotech serves South Jordan and nearby communities.
Common questions
Can pressure washing damage a concrete driveway?
Yes. Excessive pressure, a close nozzle or uneven movement can etch the surface and leave stripes. Start with a low-risk test and use a surface cleaner or qualified professional for broad areas.
Will every oil stain come out?
No. Oil can penetrate porous concrete, and older stains may lighten without disappearing. The outcome depends on how long the oil has been present and whether the slab was sealed.
