Oil-eating microbes do the heavy lifting while you sleep.

You pour a small amount over the stain, let it dry overnight, and sweep away the powder the next morning — no scrubbing, no rinsing, no harsh acids. The formula uses oil-eating microbes (tiny organisms that consume petroleum) that work deep beneath the surface to pull up petroleum-based stains from concrete, asphalt, brick, and stone. One buyer reports it removed 90% of a 25-year-old oil stain on asphalt after two days, sweeping the residue up like dust.

At 2 pounds, this 4.5 x 1.5 x 9.5-inch bottle is easy to handle and designed to work on fresh spills as well as older stains that have been sitting for years. The maker says multiple applications may be needed for severe stains, and the surface temperature should be above 60°F for best results. A few reviewers mention that the powder can irritate lungs if you stir up a cloud, so wet it slightly before brushing.

Unlike a spray degreaser that only cleans the top surface, this microbial approach reaches into the pores where the oil hides. The catch is that it works slowly — you need to plan for an overnight wait and keep rain off the area for 24 hours. Some buyers also report that it can leave a slight chalky residue that fades over time.

A poultice draws the oil out of the concrete like a magnet.

This formula uses what the maker calls “poultice technology” — it soaks into the stain, lifts the oil as it dries, and turns into a chalky dust you simply brush away. Customers note it removed a year-old oil stain from a concrete driveway after three overnight applications with a steel brush, restoring the original concrete color. It works on transmission fluid, brake fluid, and other petroleum-based messes common on garage floors and driveways.

The bottle measures 2.5 x 4.25 x 10 inches and weighs 2 pounds, making it a compact pick that still holds enough for several treatments. Unlike some competitors that require rinsing, this one leaves no liquid runoff — just dry residue you sweep up. One reviewer noted that after soaking an ATF stain overnight and scrubbing with a deck brush, it was “far more effective than Zep degreaser.”

The honest trade-off is that old stains may need three or more applications before they fully disappear, and you still have to scrub with a brush for the best results. It also does not work on epoxy-coated floors, so check your surface type before you pour.

A citrus-powered pour that lifts grease from pavers without rinsing.

Pour-N-Restore combines a citrus degreaser (a cleaner made from citrus oils) with a non-leaching absorbent (a material that traps oil but does not release it) to pull oil, food grease, and transmission fluid out of concrete and stone. One buyer reports it removed 3-year-old stains from pavers, satisfying HOA complaints, while another called it the “only product that removes oil stains on pavers.” You pour it on, let it dry to a powder, and sweep — no rinsing required. The pleasant citrus smell is a bonus compared to the chemical odor of some competitors.

The bottle measures 4.5 x 2.5 x 9.75 inches. It has a 3.9 out of 5 rating from 719 buyers, showing it works reliably for most people. The maker recommends applying on a dry day and letting the product fully dry before sweeping. One reviewer found that at 44°F the product did not dry completely to a powder and needed a stiff brush to remove, so warm weather helps.

A few buyers reported that the product had solidified in the bottle, requiring a wire to stir it, and that the coverage was less than expected due to consistency issues. If you buy it, store it upside down overnight and shake well before use to avoid the separation problem.

Spray on, let sit, rinse off — a fast degreaser for masonry surfaces.

This spray formula penetrates porous masonry (brick or stone that soaks up liquids) to remove petroleum-based stains like motor oil, gasoline, and brake fluid. The maker claims you can clean the surface in 15-30 minutes: spray directly onto the stain, let it sit to emulsify the grime, then rinse with plenty of water. It is designed to work on concrete, cement, brick, natural stone, and even asphalt, limestone, slate, and marble — making it among the most versatile options in this list.

At 1.38 pounds, the 22-ounce bottle has a spray tip that lets you target the stain precisely without wasting product. One buyer used it on engine oil stains and was impressed, though the same reviewer noted it was less effective on transmission stains. Another buyer praised it for removing all the stains from a concrete patio. However, a few reviewers warn it can permanently discolor some pavers — one said it “absolutely destroyed those pavers” — so test in an inconspicuous spot first.

The strong odor irritated one buyer’s nostrils, and another found it did not perform noticeably better than soapy water. If you prefer a fast-acting spray over a slow overnight drying method, this is worth a try — just do a spot test on valuable masonry.

An industrial-strength spray that targets both fresh and old oil spots.

Oil Spots Gone markets itself as a fast-acting spray that lifts and dissolves motor oil, grease, and automotive fluids from concrete, stone, and pavers. One buyer mentioned that after the first use, stains became much lighter, and after the second application they “disappeared completely.” Another reviewer, a father dealing with his daughters’ leaky cars, called it a standout after trying Coca-Cola, vinegar, and baking soda with only mild success. The spray bottle design makes it easy to blast a single spot without wasting product.

The package dimensions are 7.76 x 3.35 x 3.31 inches, and the bottle weighs 12.31 ounces — noticeably lighter than the 2-pound pour-and-sweep products. The maker says it works on both recent spills and older set-in stains, though some buyers strongly disagree. Several verified reviews state it “did not work, not a bit” on oil stains that were only a couple of weeks old, and one owner reported you cannot return it because it is classified as a hazardous chemical.

The polarizing reviews (some 5-star, some 1-star) mean you are taking a gamble. If it works for your specific stain, it is a fast and easy spray. If it does not, you are out the money with no return option. The included rag is a nice touch, but it does not make up for the inconsistent performance.

A budget-friendly liquid that works best on small fresh stains.

Fusion CreteCare offers a liquid degreaser formula designed to lift oil and grease from garage floors and driveways. One buyer used it on a small oil stain and said it did a “decent enough job,” though they could not judge how it would handle a larger spill. The bottle weighs 2 pounds with package dimensions of 9.45 x 3.23 x 3.15 inches, giving you a solid volume for the price. It also doubles as a general cement cleaner for restoring the original look of your flooring.

Despite the marketing claims of “advanced grease removal technology,” real reviews tell a different story. Multiple shoppers say it “cleaned no better than common soap,” and one called it “equivalent to a mild dish soap.” Another reviewer advised buyers to save their money and use a pressure washer instead, saying they would return it if possible. With a 3.3 out of 5 rating from just 54 reviews, this is the lowest-rated product in the lineup.

Fusion CreteCare is the lightest-duty option here. If you have a tiny fresh drip on a garage floor, it may get the job done. For anything older, larger, or deeper, you are better off spending a couple of dollars more on one of the pour-and-sweep products above.
