Surface cleaner, not a wand
A rotary surface cleaner passes at a constant height, which is the only way to finish a slab without stripes.
Hand-wanding a driveway leaves the arc pattern you see on half the concrete in Tracy — light bands where the tip lingered and dark ones where it did not. The pattern is permanent until the whole slab is re-cleaned.
The surface cleaner holds two jets at a fixed height and overlaps every pass. Edges, the expansion joints and the tight strip along the garage threshold are detailed by hand after the machine work.
What Tracy driveways are actually stained with
Tire marks, irrigation rust and drive-lane oil are three different problems and get three different treatments.
Rust bleed from sprinkler water is common on Tracy slabs facing an irrigated lawn strip, and it needs an oxalic treatment rather than pressure. Pressure alone just polishes the concrete around the stain.
Oil in the parking lane is pre-treated with a degreaser and dwell time before any water touches it, at $25 to $75 by severity. Tire scuff at the apron responds to heat and dwell, not more pressure.
Where the water goes on a Tracy lot
Runoff is directed to landscaping or the street gutter deliberately, never into the garage or a neighbor's pad.
On the shared-driveway lots common in newer Tracy villages, the rinse plan matters as much as the cleaning. We work down-slope and away from the threshold so nothing sheets into the garage.
Reclaim is used where a job requires it, and slurry is never pushed into a storm inlet. That matters on commercial pads and HOA common areas, where San Joaquin County discharge rules apply.
Sealing Tracy concrete, and when it is worth it
Clean plus seal is $0.77 per square foot and pays off on stamped, colored or newer decorative concrete.
Plain gray broom-finish concrete does not usually need sealing in Tracy; it holds up and recleans easily. Stamped and colored surfaces do, because the pigment layer is what fades first under valley sun.
Sealing is scheduled as a return pass after the slab is fully dry, which in Tracy summer is the same afternoon and in winter is a separate day.
Most Tracy driveway work lands March through October, when Tracy afternoons are warm enough for degreaser dwell and sealer cure without a rain window interrupting it.
