An oil stain treatment is quoted by how many spots need degreasing and how long the oil has been soaking in, not by driveway size. A fresh stain from a weekend of dripping usually lifts in one pass; oil baked into unsealed concrete for a year or more may only lighten instead of disappearing.
How completely an oil stain comes out depends on the concrete, not the degreaser. Sealed concrete holds the oil near the surface, where a degreasing agent breaks it down and a rinse carries it away in one visit. Unsealed, porous concrete lets oil migrate deeper into the slab, and a stain that's had months to soak in there sometimes just gets lighter, not gone.
Garage floors behave differently for a separate reason — without rain and sun cycling over the stain, oil sitting on a garage floor stays put and doesn't spread, but it also never fades on its own, so garage stains tend to be older and more set-in by the time someone calls.
Is this billed as its own job or added to a driveway wash?
Most oil stain work in Cleveland gets quoted as a per-spot add-on to a driveway or garage floor cleaning rather than a flat callout on its own. A single fresh spot from a leaking transmission takes one application and a short dwell time; two or three old stains scattered across a garage floor take longer, because each one gets treated and rinsed separately before the floor is washed together.
- Fresh spot: one application
- Old stain on bare concrete: multiple applications with dwell time between each
- Several stains on one floor: priced and treated per spot
What happens if a stain doesn't fully lift?
Some stains are permanent by the time they're reported — usually motor oil or transmission fluid that sat on unsealed concrete for a long stretch before anyone tried to treat it. A second application often lightens it further, but setting that expectation up front matters more than promising a result the concrete won't give back.
Do you treat stains before the concrete gets sealed?
Yes, and it needs to happen in that order — sealing over an existing stain locks it in permanently under the coating. If a driveway or patio is already scheduled for sealing, mention any visible stains when booking so the degreasing step happens first and the seal goes down on clean concrete.
Send a picture of the stain when requesting a quote, or call (216) 999-4953 with the surface type — driveway, garage floor, or patio — so the estimate accounts for it.
Can an oil stain be removed from a garage floor, not just a driveway?
Yes — garage floors get the same degreasing process, though stains there are often older since rain and sun never work on them between visits. Expect a floor with multiple stains to take longer than treating one fresh spot outside.
Should I seal my driveway before or after stain treatment?
After. Sealing over a stain traps it under the coating permanently, so any visible oil spots need treating first. If sealing is already scheduled, mention the stains when booking so both jobs happen in the right order.
Will the degreasing chemical discolor the concrete around the stain?
No — the treatment is formulated to lift oil without bleaching or etching the surrounding surface, and it's rinsed off rather than left to sit. The concrete around the spot ends up the same color it started, just without the stain.
How soon can I park on the driveway again?
Once the surface is rinsed and dry, which is typically the same day. Avoid parking directly over a freshly treated spot until it's fully dry, since a warm tire can re-set a trace of oil that hasn't finished lifting.
