Oil does not sit on concrete, it soaks into it, which is why pressure washing alone cleans the concrete around a stain and leaves the stain looking worse. Removing it takes a degreaser with real dwell time, drawing the oil back to the surface before it is washed away. Here is what comes out, what does not, and what it costs.
Someone from our team will reach out to you shortly.
Concrete is porous. A fresh oil drip sits on the surface for a matter of hours and then wicks down into the pore structure, and once it is in there, water hitting the top of the slab cannot reach it. That is the whole reason a pressure-washed driveway often looks worse afterwards: the surrounding concrete came back to its original colour and the stain did not move, so the contrast went up.
\nWhat actually works is drawing the oil back out. A degreaser is applied and given time to penetrate and emulsify the oil in the pores, and only then is it washed off, taking the oil with it. Deep or old staining sometimes needs the cycle repeated. It is not a faster or more powerful machine; it is chemistry and patience, and any company telling you otherwise is going to leave your stain where it is.
\nThe most common one. A degreaser with dwell time pulls it back to the surface. Age is the single biggest factor in how much comes out.
Dyed red and it stains more visibly than motor oil, but it responds to the same degreasing approach.
Coolant leaves a bright residue that cleans up readily. Brake fluid can attack a sealed surface, so a sealed driveway may show a dulled patch underneath once the stain is gone.
Orange staining from iron in irrigation water or from fertilizer granules. It needs a rust-specific treatment; degreaser does nothing to it and neither does pressure.
Part rubber, part plasticizer migrating out of the tire into the concrete. The rubber comes off; the migrated plasticizer is the stubborn half.
This is surface damage rather than a stain. Cleaning makes it more visible, not less, and we will say so before starting rather than after.
Each needs its own solvent and its own approach, and some will not come off concrete without taking surface with them. Worth a photo before you assume either way.
Dark shadowing under trees and where wet leaves sat. Not oil at all, and it responds to a solution rather than a degreaser.
Oil, rust, tannin, and etching look similar on a photo and need four different treatments. Getting this wrong is why a lot of stain removal fails.
Degreaser for petroleum, rust remover for iron staining, a solution for organics. Dwell time is the part that cannot be rushed, and it is the part that gets skipped.
Treating a stain in isolation leaves a clean patch on a dirty driveway, which looks worse than the stain did. The whole slab gets an even surface-cleaner pass so the finish is uniform.
Deep staining often lifts noticeably further on a second cycle. We will tell you when a stain has reached the point where another pass will not change it.
Two things matter more than anything else. First, fresh drips come out easily and old ones do not, so dealing with a leak and a fresh spot in the same week is worth far more than any product. Second, a sealed driveway keeps oil in the sealer rather than in the concrete, which turns a permanent stain into a cleanable one.
\nIf your driveway also carries a winter of road salt and de-icer, clearing that each spring matters for the concrete itself rather than just the look, because the salt keeps working on the surface as long as it is there. Oil stain work is quoted as part of driveway cleaning, from $80, and we handle it across the whole Salt Lake, Davis, and Weber County corridor.
