Driveway cleaning, without the zebra stripes
Driveways, paths, patios and garage floors. Get matched with crews running proper surface cleaners - and find out which of your stains are dirt and which are chemistry before you pay anyone.
What is driveway & flatwork cleaning?
Driveway cleaning covers the flat, hard surfaces around a house - driveway, paths, patio, steps, garage floor. Unlike walls, sound concrete genuinely tolerates high pressure, and Consumer Reports puts driveways and walkways in the 1,500-3,000 psi band. The work is done with a surface cleaner, a round enclosed attachment with rotating jets that lightens the slab evenly. General grime lifts mechanically. Oil, rust and tannin do not, and need targeted treatment first.
Signs you need driveway & flatwork cleaning
- The slab has gone patchy green-black in the shaded strip along a wall or under trees, and is slippery after rain
- There is a clear clean rectangle where a car, a planter or a bin has been sitting, and everything around it is several shades darker
- Orange rust plumes are spreading from a metal furniture leg, an irrigation head or a rebar tie
- Dark tyre-scrub marks and a black drip pattern have built up where a vehicle habitually parks
- A white powdery bloom keeps returning on pavers or on the face of a concrete step
- You are about to seal or re-sand the surface and it has to be genuinely clean first
- The jointing sand has washed out of a paver patio and weeds are colonising the gaps

How driveway & flatwork cleaning actually works
Identify the stains before quoting the slab
General darkening is biological and mechanical and comes off with the surface cleaner. Oil, rust, tannin from leaf litter and efflorescence do not - each needs its own pre-treatment, applied and dwelled before the main clean.
Watch forA quote by square foot with no mention of the oil patch. You will get a beautifully clean driveway with the oil patch still in it, and an argument about whether that was included.
Clear, sweep and pre-treat
Vehicles, bins, furniture and planters come off. Loose debris is swept rather than blasted into the beds. Pre-treatment goes onto the identified stains and is given time to work before any pressure is applied.
Watch forDebris being flushed straight into a flower bed, a drain grating or a French drain. It compacts there and you deal with it later.
Surface clean in overlapping passes
The surface cleaner is walked in overlapping passes at a consistent speed so the slab lightens uniformly. Edges, joints and awkward corners are then detailed by wand - the small proportion of the job where a wand is legitimately used.
Watch forA bare wand used across the open slab. It leaves permanent striping, because the operator cannot hold a constant distance and speed and each pass removes a different amount of cement paste. This is the defining defect of a cheap driveway job and it does not fade.
Handle pavers differently from poured concrete
On pavers the jointing sand comes out with the dirt. The joints are re-sanded after the surface has dried, and on a polymeric system the new sand is activated per its instructions. Skipping this leaves the pavers free to shift and the joints free to grow weeds.
Watch forA paver clean quoted with no re-sanding line item. That is not a complete job - it is half a job that leaves the patio less stable than it was.
Rinse out, then decide about sealing
The whole area is rinsed clear of residue and slurry, including the run into the street or the drain. Sealing, if you want it, happens later once the slab is genuinely dry through, not on the same visit.
Watch forA same-day seal upsell. Sealing over trapped moisture clouds the finish and can leave you with a milky driveway that has to be stripped.
What does driveway & flatwork cleaning cost?
Flatwork is generally priced by the square foot, quoted after the surface is seen. Stain pre-treatment, paver re-sanding, hot water for grease and sealing are separate line items rather than part of the base rate. The Cost Guide explains how those pieces stack up.

When driveway & flatwork cleaning is the wrong call
When saying yes is the wrong move:
- The concrete is already spalling or crumbling. If the surface is flaking, pitted or losing aggregate, high pressure accelerates it. What you are looking at is a failed or freeze-damaged slab, and cleaning it makes the failure more visible, not less.
- The finish is decorative. Stamped, coloured, exposed-aggregate and acid-stained concrete can lose colour, expose more aggregate or be visibly altered. These need a much gentler approach and, often, resealing afterwards - get it quoted as decorative work or leave it alone.
- The stain is rust or oil and you are being sold pressure. Rust is iron oxide in the pores and oil has soaked in. More pressure removes clean concrete from around the stain and leaves a lighter halo with the stain still in the middle. This is a chemistry job.
- It is efflorescence. That white bloom is salt migrating out of the concrete or the bedding. Washing removes today's bloom and the moisture behind it makes tomorrow's. Until the moisture path is dealt with, you are on a treadmill.
- You expect old concrete to come back white. Decades of weathering, carbonation and embedded staining do not reverse. A good clean makes a 20-year-old slab look like a well-kept 20-year-old slab, and an honest contractor will say so before starting.
- It is an asphalt driveway. Asphalt is a flexible bituminous surface, not concrete. Concentrated pressure can dislodge aggregate and damage the binder, particularly in warm weather when it is softest. Ask specifically what pressure will be used and expect a much gentler answer.
Can I do this myself?
Reasonable to DIY
- Cleaning a sound poured-concrete path, patio or driveway with a rented machine and a rented surface cleaner - hire the attachment, not just the machine
- Testing the pressure in an out-of-sight corner before starting on the visible area
- Sweeping and clearing the area, and pre-treating an oil patch with a dedicated concrete degreaser per its own instructions
- Re-sanding paver joints yourself once the surface has fully dried
Call a licensed pro
- Any decorative finish - stamped, coloured, acid-stained or exposed aggregate
- Rust, tannin and set-in oil staining, where the pre-treatment does the work and the wrong product can permanently discolour the slab
- Large areas, where a hand-held wand will visibly stripe the whole surface before you finish
- Anywhere the slurry runs to a storm drain, a watercourse or a neighbour's ground
- Sealing, which is far less forgiving of moisture and application error than the cleaning is
What to check when hiring for driveway & flatwork cleaning
- Are you using a surface cleaner across the open slab, or a wand? The single most predictive question for how your driveway will look. A wand across open concrete means stripes, and stripes are permanent.
- What is your plan for the oil patch and the rust marks specifically? Forces the stains onto the quote as named items instead of leaving them as a disappointment. Expect to hear about a pre-treatment and a dwell time.
- Do you have hot water available, and will this job need it? Heat helps with grease, gum and oil in a way that raw pressure does not. Not every crew carries a hot-water machine. If your problem is grease, this matters.
- Is re-sanding the paver joints included? The clean removes the jointing sand. If it is not going back, the job is incomplete and your pavers are less stable than before.
- Where is the slurry going, and is that allowed here? Wash water from flatwork carries dirt, oil residue and detergent. Discharge to a storm drain is regulated in many places, and it is the contractor's job to know the local position.
- What will not come out, honestly? A driveway with a decade of embedded staining will not go uniform. Getting the realistic answer up front prevents the argument at the end.
- If I want it sealed, when should that happen? You are checking that they will not seal over damp concrete. The answer should be a separate visit after the slab has dried through, not the same afternoon.
