If you turn wrenches for a living, you already know the laundry problem. Engine grease, gear oil, and brake dust grind into the weave of your work shirts and pants, and a normal cycle in the washer just smears it around. The right degreaser breaks the bond between that petroleum gunk and the fabric so it actually rinses away instead of setting in as a permanent shadow.
We put the most popular shop and laundry degreasers through real-world abuse on cotton tees, poly-blend coveralls, and heavy canvas work pants stained with motor oil, chain lube, and ground-in black grime. We judged each one on how well it lifted set-in oil, whether it harmed the fabric or color, how strong the fumes were, and how easy it was to use at the laundry sink. Here are the seven that earned a spot, ranked best first.

1. Zout Triple Enzyme Formula Laundry Stain Remover: Best Overall
Zout earned the top spot because it walks the line that matters most for mechanic clothes. It is aggressive on petroleum grease and oily food stains, yet it is genuinely color-safe and gentle on the fabric, so you can use it on every shirt in the hamper instead of just the ruined ones. The triple enzyme formula chews through oil while also handling the sweat, blood, and grime that build up on a work collar, which is why it beat single-purpose solvent cleaners in our side-by-side soak tests.
The honest weakness is patience. On grease that has been baked in by a hot dryer over several washes, one spray and a normal cycle will fade the stain but not always erase it the first time. We got the best results spraying it on, working it in with an old toothbrush, letting it sit for ten to fifteen minutes, then washing in the warmest water the garment allows. The trigger bottle is also slow going if you are pretreating a full set of coveralls, so heavy users may want to keep a second bottle on hand.
- Triple enzyme blend targets grease, protein, and oxidizable stains at once
- Trigger sprayer for direct pretreat on collars, cuffs, and ground-in spots
- Color-safe and chlorine-free, works in cold or warm wash water
Pros: Lifts set-in motor oil and food grease better than most laundry sprays; Gentle enough to use on colored shirts and poly blends without fading; Mild scent compared to solvent shop cleaners
Cons: Very old, fully cured grease may need a second application; Trigger spray covers small areas slowly on full coveralls
2. Krud Kutter Original Concentrated Cleaner and Degreaser: Best for Heavy Grease
Krud Kutter is the bottle you reach for when the stain is thick and fresh. As a water-based concentrate it grabs heavy grease, bar oil, and that black sludge that coats your hands after a brake job, and it does it without the eye-watering solvent smell of traditional shop degreasers. We sprayed it full strength onto greasy canvas work pants, let it dwell, and watched it loosen deposits that a standard detergent simply could not move.
Because it is a true degreaser and not a gentle laundry aid, the trade-off is that you have to respect dwell time on colored clothes. Left to sit too long on dark or printed shirts, the strong concentrate can lighten the dye slightly, so we always spot test a hidden seam first and rinse promptly. Used with that small bit of care, it is the most powerful grease cutter on this list and doubles as a hard-working cleaner for your workbench and tools.
- Water-based concentrate cuts heavy automotive grease without harsh solvents
- Can be used full strength as a pretreat or diluted for a soak
- Non-toxic and biodegradable, no strong solvent fumes
Pros: Excellent on thick, fresh grease and chain lube; Versatile as both a clothing pretreat and a shop surface cleaner; Rinses clean and is gentle on most colorfast fabrics
Cons: Strong concentrate can dull some dark dyes if left too long; Best results need a spot test on delicate or printed garments
3. Grease Monkey Wipes Heavy Duty Cleaning Wipes: Best Pretreat Wipes
The smartest stain strategy is to never let grease set in the first place, and that is exactly what Grease Monkey Wipes are built for. These pre-moistened citrus wipes live in your toolbox or glovebox, so the moment you smear oil on a sleeve you can scrub the spot before it dries and bonds to the cotton. In our testing, a stain blotted with one of these wipes within minutes washed out far more completely than the same stain left to cure overnight.
They are a pretreat tool, not a laundry product, and that defines their limit. A wipe is perfect for one cuff or a single splash, but you would burn through a whole pack trying to treat a full pair of greasy coveralls, which is not practical. They also struggle with old, hardened grease that has already worked deep into the fibers. Think of them as prevention you carry with you, paired with a proper bottle degreaser back at the laundry sink.
- Citrus-based cleaning wipes lift grease from skin and fabric on the spot
- No water needed, ideal for treating a stain before it sets at the job site
- Textured wipe scrubs ground-in grime out of the weave
Pros: Treat a fresh stain immediately so it never has a chance to set; Portable and convenient for road service and field techs; Pleasant citrus scent instead of harsh chemical odor
Cons: Not economical for treating large areas or full loads; Less effective on grease that has already cured into the fibers
4. OxiClean Versatile Stain Remover Powder: Best Soak Booster
OxiClean is the workhorse for treating a whole hamper of work clothes at once. Dissolved in warm water as a presoak, the oxygen action goes after oily film and the gray dinginess that builds up across an entire load, which a targeted spray cannot reach evenly. We soaked a batch of oil-spotted tees overnight in an OxiClean solution and they came out noticeably brighter and far less greasy before the wash cycle even started.
Where it falls short is the concentrated, single-point grease stain. A thick blob of chain lube needs a real degreaser worked directly into the fiber first, because the diluted soak alone will fade it but not fully remove it. The powder also depends on warm water to dissolve and activate, so cold-only soaks underperform. Used as a booster and presoak alongside a spot pretreat, it is one of the best value tools you can keep on the laundry shelf.
- Oxygen-based action lifts oil and grime when used as a presoak
- Chlorine-free and color-safe for whites and colors alike
- Doubles as an in-wash booster added to every greasy load
Pros: Great value for soaking multiple garments at once; Brightens dingy work whites while it degreases; Safe to mix with regular detergent in the machine
Cons: Heavy single-spot grease still needs a dedicated pretreat first; Powder needs warm water to dissolve and activate fully
5. Fast Orange Pumice Hand Cleaner: Best Citrus Spot Treat
Most mechanics already have a tub of Fast Orange by the sink for their hands, and it turns out the same citrus power works as a clothing pretreat in a pinch. The d-limonene from orange peel dissolves grease, tar, and asphalt that water-based cleaners often just slide over, and the fine pumice gives you something to scrub ground-in grime with. We rubbed it into a tar-spotted work shirt, let it sit, then laundered it, and the spot lifted better than with detergent alone.
The catch is that it was designed for skin, not fabric, so you have to use it thoughtfully. The pumice grit needs to be rinsed out completely before the garment goes in the machine, or you will find grit in your washer. It is also a thick hand cleaner rather than a sprayable laundry product, so spreading it across a large area is more work. As a convenient spot treatment using something you already own, though, it punches well above its weight on greasy and tarry stains.
- Natural citrus power dissolves grease, tar, and oil
- Fine pumice grit helps scrub ground-in grime out of the weave
- Lanolin and aloe formula is easy on skin during application
Pros: Already in most shops, so it doubles as a clothing pretreat; Citrus solvent cuts tar and asphalt that water-based products struggle with; Biodegradable and a fresh orange scent
Cons: Pumice grit must be rinsed out fully before washing; Thicker than a sprayer, so application takes more effort
6. Carbona Stain Devils Grease and Oil Remover: Best Targeted Remover
Carbona takes a different approach by selling stain removers tuned to specific stain families, and the Grease and Oil version is the one mechanics want. Instead of a do-everything cleaner, the chemistry is aimed squarely at petroleum oils, lubricants, and grease, which means it can be more effective on the exact problem you have. The precise applicator lets you treat a single spot on a good shirt without dousing the whole thing, which we appreciated on nicer poly-blend uniforms.
The limitation is volume and matching. The bottle is small and meant for targeted spots, so it is not the product you grab to treat a whole bin of filthy coveralls. You also need to use the correct formula for the stain, and a shop rarely has just one kind of mess, so you may end up wanting more than one of their bottles. For careful, targeted grease removal on garments you care about, it is hard to beat.
- Formulated specifically for the grease, oil, and lubricant stain group
- Precise applicator targets individual spots without soaking the garment
- Color-safe and usable on a range of washable fabrics
Pros: Chemistry tuned for oil and grease rather than a general cleaner; Small bottle is precise and travels well; Works on both fresh splashes and older set-in marks
Cons: Small bottle is not built for high-volume or full-load use; Needs to be matched to the correct stain type for best results
7. Purple Power Industrial Strength Cleaner and Degreaser: Best Big-Batch Value
For a busy shop washing piles of filthy uniforms every week, Purple Power is the big-batch option. It is a heavy industrial concentrate that dilutes a long way, so a single large jug can pretreat or soak load after load of grease-soaked clothing without running out. On the worst engine-grime coveralls we tested, a diluted soak in Purple Power loosened deposits that lighter laundry products never touched.
That raw power comes with the most important warning on this list. It is a strong alkaline degreaser built for engine parts and concrete, so using it at full strength on clothes can fade colors and, over time, weaken fibers. You must dilute it properly, keep the dwell time short, and rinse thoroughly. Treated with respect and proper dilution, it is the most economical way to keep a fleet of work clothes degreased, which is exactly why it earns a place at the value end of the list.
- Industrial-strength concentrate dilutes for soaking heavily soiled clothes
- Cuts engine grease, oil, and grime across large loads
- Large jug delivers strong value for high-volume shop laundry
Pros: Powerful grease cutting for the toughest shop clothing; Dilutes far, so one jug treats many loads; Also handles floors, tools, and engine parts
Cons: Strong alkaline formula can fade or weaken fabric if used too strong; Must be diluted carefully and not left on clothes too long
Frequently Asked Questions
Will degreaser ruin or fade my work clothes?
It depends on the type and how you use it. Color-safe laundry products like Zout and OxiClean are formulated to be gentle on dyes and most washable fabrics, so they are safe for everyday use on colored shirts and uniforms. Strong industrial concentrates like Purple Power or Krud Kutter are far more powerful and can fade dark colors or weaken fibers if used full strength or left to dwell too long. The safe rule is to always spot test a hidden seam first, follow the dilution instructions, keep dwell time reasonable, and rinse thoroughly before machine washing.
How do I get set-in, dried grease out of clothes that has already been through the dryer?
Set-in grease is the hardest case because the dryer heat bakes the oil into the fibers. Your best shot is to rewet the stain, work a real degreaser deep into the fabric with an old toothbrush, and let it dwell ten to fifteen minutes before washing. Wash in the warmest water the garment allows, then air dry and check the spot before it ever sees the dryer again. Heavy set-in stains often need two or three rounds of pretreat and wash before they fully release, so do not give up after the first cycle, and never run it through the dryer until the stain is gone.
Can I just use my hand cleaner like Fast Orange on my clothes?
Yes, in a pinch, and many mechanics do exactly that. Citrus hand cleaners use the same orange-peel solvent that cuts grease and tar, so rubbing a little into a fresh stain and then laundering works surprisingly well. The one thing to remember is that pumice-based hand cleaners contain grit that you must rinse out completely before the garment goes into the washer, or you risk leaving residue in the machine. Hand cleaner is a great spot treatment for something you already own, but for full loads a dedicated laundry degreaser or soak is more practical.
Should I wash my greasy mechanic clothes separately from regular laundry?
Absolutely. Grease and oil can transfer from heavily soiled work clothes onto cleaner garments in the same load, leaving gray, oily marks on everything. Always wash shop clothes in their own load, ideally after pretreating the worst spots. It also helps to run an extra rinse and, every so often, run an empty hot cycle with a cleaner to flush grease residue out of the washer drum itself so it does not build up and redeposit on future loads.
Is hot or cold water better for washing out grease?
Warm to hot water is generally better for grease because heat helps liquefy the oil so it can rinse away, and many oxygen-based products like OxiClean need warmth to activate fully. That said, always check the care label first, because hot water can shrink some fabrics and set certain other stains like blood or protein. A good middle path for mixed mechanic clothing is to pretreat the grease spots with a degreaser, then wash in the warmest water the garment can safely handle.
Our Verdict
For most mechanics, Zout Triple Enzyme Formula is the best all-around pick because it cuts grease and oil aggressively while staying color-safe enough for every shirt in the hamper, making it the one bottle you can reach for without worrying about ruining good clothes. If your stains are thick, fresh, and brutal, our runner up Krud Kutter Original is the more powerful grease cutter and doubles as a shop cleaner, just respect the dwell time on colored fabrics. Pair either one with an OxiClean presoak and a pack of Grease Monkey Wipes in your toolbox, and you have a complete system for keeping work clothes clean shift after shift.
