5 Best Grease Stain Remover | Set-In Grease, Gone by Wash Two

A tiny, single-purpose bottle built for the oil stain you thought was already ruined.

Where an all-purpose spray spreads itself thin, Carbona Stain Devils #6 does exactly one job: fat and cooking oil. That narrow focus is the whole point. The bottle’s target list runs to clay, dirt, food colouring, grass, lipstick, make-up, mascara, mud, pollen, rouge, and toothpaste — but its real reputation is built on grease and cooking oil that has already set. Buyers report it pulling oil stains out of clothes even after the mark has sat for several hours, and owners mention it saving garments with both fresh and already-washed-and-dried grease.

Two rounds with this and spots tend to disappear, and unlike chlorine bleach or heavy brand spot products, it has not been reported to strip dye from a coloured garment. It is dermatologically tested, so it is gentle on bare hands during pre-treating. It is safe on washable, water-safe fabrics including cotton, wool, nylon, rayon, polyester, acrylics, and blends. The exclusions matter, though: it is not for silk, acetate, carpeting, or upholstery, so keep it off the good tablecloth and the sofa.

Then there is the size question, and it is real. The three 1.7 Fl Oz bottles in the pack do not go far if you treat stains weekly, and the per-bottle cost sits high against a bulk degreaser. It is a specialist’s tool: buy it for the set-in fat stain you care about, not for everyday spills that a general pre-treat will handle. Against the Vanish spray in the top spot, this one trades everyday versatility for concentrated power on the hardest oil marks — and it gives up silk, acetate, carpeting and upholstery to get there.

One 32 oz bottle that goes from the stovetop to the driveway without breaking stride.

For the money, this is the most coverage you get in the lineup: a two-pack of 32 oz bottles that handles the grill, the stovetop, the patio, the garage floor, and the laundry prewash from the same jug. The formula dissolves grease, oil, and dirt from any washable surface. It is USDA approved for use at food service facilities (A1, A4, A8), so it is cleared for food prep areas. It is also biodegradable, solvent-free, and noncorrosive, so it will not eat through the surfaces you spray it on.

The concentrated formula is the other half of the appeal. Ultra concentrated means you can clean floors, walls, driveways, grills, exhausts, patios, outdoor furniture, tile, boats, automotive wheels, tools, and carpet stains from the same jug, and the laundry grease-stain use means you are covered on fabric too. Customers note that stubborn sticky grease can melt off almost immediately once the spray hits it. One professional engine builder is noted using it full strength for final cleaning of engine parts — spray, brush the oil passages, rinse with hot water, apply WD-40, blow dry with compressed air.

The honest picture is more mixed here than the spec sheet suggests. Quality scores on this one divide people — some call it the best degreaser they have used, others have not had the same luck, and old oil stains in particular are a coin flip depending on the surface and how long the mark has been there. The scent is another point buyers disagree on. Treat it as a capable all-rounder for fresh grease and general grime rather than a guaranteed rescue for a stain that has been baked on for months. For fabric-only set-in stains, the Carbona above is still the more targeted tool.

An 18 oz spray that doubles as a kitchen degreaser and a laundry pre-treat in one bottle.

Here is the bottle for the greasy stovetop and the shirt you were wearing while you cooked it. Grease Relief is built as an all-purpose grease remover for the kitchen, bathroom, car, cookware, and laundry. The formula is non toxic, biodegradable, fume free, and dye free, so it degreases a stovetop without a chemical smell. It is made in the United States, and the maker says it will not harm washable colours or fabrics — it is even listed as working well for washing your hands.

The laundry side is where the reputation really lives, and the story to know is butter. Reviewers point out a butter spill across a shirt and pants, sprayed once on each mark and then washed, coming out clean on the first cycle — a strong result for a stain that usually resists a standard wash. A separate account tells of an aquaphor mark on clothing that survived the first spray-and-soak attempt but lifted fully on a second round of the same process. Expect that two-pass pattern on tough, waxy stains. For fresh, ordinary kitchen grease, the results land far more reliably.

What to keep in mind is that this is not a guaranteed miracle worker. Grease removal on the harder cases splits opinions — the biggest talking point in its reviews is that it works well on some stains and misses on others, and a few owners find it priced higher than they would like. There is also a leakage gripe: some bottles have been reported arriving with a compromised seal and leaking in transit. Sized at 18 oz, it is a compact bottle compared to the two-pack of 32 oz bottles in the Oil Eater above.

A 32 oz workshop spray that cuts engine grease and road grime, towel included.

Shoppers say asphalt and sticky black road grime on car paint coming off in seconds with this 32 oz spray, after several ordinary washes had failed — and that is the kind of residue no fabric spray touches. It cuts through grease, grime, and oil, and it is listed as safe on metal, concrete, finished floors, tools, automotive parts, appliances, vinyl, fiberglass, and laminate — a long, honest list of the surfaces you would actually be spraying in a garage. The bottle arrives with a microfiber washable cleaning towel, so you have everything you need from the start. The formula is EPA Safer Choice certified and plant-based.

The same bottle also earned praise for heavy kitchen grease after three other products were tried and fell short. On oily engine parts it breaks down the oil well, though rust is a job it will not win. The format is note too: on built-up, baked-on grease, users find a non-abrasive scouring pad is needed after the dwell time — the bundled microfiber cloth alone is not enough on the worst of it. Let the spray sit, then work it.

The formula does have rules you cannot ignore. It is not for use on silk, leather, suede, faux stainless steel, drywall, unfinished wood surfaces, painted surfaces, or unsealed stone — the painted-surface exclusion is the one that catches people out, so test a hidden spot before you spray a car panel or a cabinet door. For grease and oil on hard surfaces, though, this is the pick of the group. It sits at the premium end alongside the Oil Eater as the two heavy hitters of the lineup, with the towel sweetening the deal. If your grease lives on clothing, the two are the wrong shelf entirely.
