How to Get Oil and Grease Stains Out of a Fort Myers Driveway

Getting an oil stain out of a concrete driveway comes down to chemistry and heat, not just pressure. A fresh drip lifts easily if you absorb it right away and hit it with a degreaser. A set-in stain that has baked into the concrete under the Fort Myers sun needs a degreaser left to dwell, some scrubbing, and hot-water pressure - often two or three passes. And an old, deep stain will usually lighten dramatically rather than vanish completely, because the oil has soaked down into the pores of the slab. Here is an honest, step-by-step look at what works on a Lee County driveway and what does not.

Why oil is so hard to get off concrete

Concrete looks solid, but it is porous - full of tiny channels that wick up whatever lands on it. When motor oil, transmission fluid, or cooking grease hits the surface, it soaks in rather than sitting on top, and Southwest Florida's heat speeds that up: a slab baking at surface temperatures well over 100 degrees in a Fort Myers summer draws the oil deeper by the hour. That is why a garden hose does nothing and why the stain seems to come back after it dries - you cleaned the surface, but oil down in the pores wicked back up. The fix has to pull the oil out of the concrete, not just off it, which means a degreaser that breaks the oil down plus enough heat and agitation to float it to the surface.

Fresh spill: act in the first hour

• Absorb, do not spread. Cover the puddle with cat litter, baking soda, cornstarch, or a commercial oil absorbent and press it in. Let it sit a few hours (overnight for a big spill) to draw the oil up, then sweep it into a bag - do not hose it away.
• Keep it out of the storm drain. In Fort Myers most driveway runoff feeds straight to storm drains that empty into the Caloosahatchee and the canal system, and washing oil down them is both harmful and against Lee County stormwater rules. Sweep the absorbent up and bag it.
• Degrease the shadow. Once the bulk is absorbed, work a degreaser or grease-cutting dish soap into the remaining stain, scrub with a stiff nylon brush, and rinse. Caught this early, most fresh stains come out completely.

Set-in stain: the step-by-step

1. Wet the area and apply a concrete degreaser. Use a purpose-made alkaline degreaser or a citrus-based cleaner made for concrete, applied generously over the whole stain.
2. Let it dwell. Give it 10 to 20 minutes to break down the oil - but do not let it dry out in the sun. Re-wet it if it starts to. This dwell time is where the real work happens.
3. Agitate. Scrub hard with a stiff brush to work the degreaser down into the pores and lift the oil toward the surface.
4. Rinse with hot-water pressure. Hot water melts and mobilizes oil far better than cold, which is why professional crews run hot units on grease. A surface cleaner gives an even rinse without wand stripes.
5. Repeat. Deep stains almost always need two or three full cycles. Each pass pulls out another layer.

Will a pressure washer alone remove it?

No - and this is the most common mistake. Pressure moves water fast, but oil is not loose dirt you can blast away; it is bonded into the concrete and has to be chemically broken down first. Blasting a bare stain at full pressure with cold water mostly just spreads it and risks etching the slab. The order that works is degreaser first, dwell, agitate, then hot-water pressure to carry it off. On pavers there is an extra caution: a close, high-pressure stream blows out the polymeric sand in the joints, so pavers should be degreased and cleaned at a controlled pressure and re-sanded if needed. This is the same reason we favor the right method over raw force across Lee County.

When a stain will not fully come out

Be honest with yourself about age. Oil that has been soaking into a driveway for months or years has migrated deep into the slab, and even a professional cleaning will usually lighten it to a faint shadow rather than erase it. At that point the options are a poultice (a paste that draws oil out over 24 to 48 hours), resurfacing, or accepting the shadow and sealing the concrete so it does not get worse. A good crew will tell you up front whether a stain is likely to clear or only fade - anyone promising a decade-old grease stain will vanish completely is overselling.

How to keep it from happening again

The best protection is a concrete sealer. A sealed driveway keeps oil sitting on the surface instead of wicking into the pores, so the next drip wipes up in minutes instead of becoming a permanent mark. Sealing also helps the slab shrug off the algae and rust staining that Fort Myers humidity and hard irrigation water cause. Beyond that: park a drip pan under a leaking vehicle, keep a bag of absorbent in the garage for fast cleanup, and clean spills while they are fresh - the single biggest factor in whether a stain ever comes out is how quickly you got to it.

Frequently asked questions

Does bleach remove oil stains from concrete? Not really. Bleach can lighten the discoloration a little but it does not break down or lift the oil itself, so the stain returns as the oil wicks back up. A degreaser made for concrete, plus hot water and scrubbing, is what actually removes it.

Is an oil stain damaging my driveway or just ugly? For most driveways it is cosmetic - surface oil stains the concrete but does not structurally harm sound slabs. The reason to remove it is appearance and slip safety, and to keep it from spreading or being tracked indoors.

Can you get an old, set-in oil stain completely out? Often it can be lightened a great deal, but a stain that has soaked in for a long time usually leaves a faint shadow. A professional degrease-and-hot-water cleaning gets it as far as it will go; a poultice or sealing handles the rest.
