Set-In Grease Stains on Clothes, Including After the Dryer
Everyone says a grease stain that went through the dryer is permanent. It is not, but it takes a different approach than a normal wash, and the steps below explain it.
The short answer
A dried grease stain needs time with the treatment on it, not a hotter wash. Spray OxiClean MaxForce on the set stain, leave it for at least an hour and up to days on the worst cases, then wash warm. It holds 4.7 stars from 15,549 ratings on Amazon (November 2026).
Why does this happen?
Grease is oil, and oil does not dissolve in water; a normal wash moves it around with surfactants and lifts some of it, which is why fresh grease often washes out and old grease does not. Each wash-and-dry cycle pushes the remaining oil deeper into the fiber and oxidizes it, darkening and stiffening the bond. By the time a stain has been dried twice, a normal wash will not reach it. You need a cleaner or a long enzyme soak that can get to oil that is deep inside the fibers.
That is why the steps below are mostly waiting. The spray's enzymes and oxygen ingredients work slowly on dried residue, and the fact that the label lets you leave it on for days is the main reason it works. Agitation and heat in a quick rewash, by contrast, just reseal what the spray was loosening.
The fix, in order
The steps are ordered cheapest first. Stop at the one that solves it and skip the rest; the product is there only for where the free steps run out.
Free step
Find every stain before you start
Hold the garment up to bright light and mark grease spots with chalk or tape; dried grease hides in flat light and reappears after ironing, which sets it further.
Free step
Degrease the surface first
Work a drop of dish soap into each spot and rinse. This removes the oil on the surface so the treatment in the next step reaches the set part of the stain instead of being used up on the easy top layer.
The product step
Spray MaxForce and wait, properly
Saturate each stain with OxiClean MaxForce. For a fresh set stain, an hour; for a dryer-set stain, leave the garment for one to several days (the label allows up to a week), keeping the spots damp with a light re-spray if they dry out. Then wash on the warmest setting the fabric allows.

Habit step
Inspect in daylight before drying
Air-dry and check. If a faint mark remains, spray it and let it sit one more time. Do not put the garment in the dryer until the stain is gone.
The evidence, in tiers
Tier 1 · The method
Enzyme and oxygen treatments left on for a long time are what the textile industry uses for set stains. The label says how long to leave them on, and most people leave them on for less time than that and then judge the product anyway.
Tier 2 · This product
OxiClean MaxForce holds 4.7 stars from 15,549 ratings on Amazon (November 2026).
We have not run a dryer-set test garment for this guide. The method follows the product's label dwell times, and the rating record is quoted above.
Tier 3 · What owners report
Owners who leave the treatment on for several days report the best results on exactly the case people doubt most, dryer-set grease. The main complaint comes from people who left it on for one hour on a two-year-old stain and called that a failure.
The alternatives, conceded where they win
| Option | What it is | The honest verdict |
|---|---|---|
| OxiClean MaxForce spray | Enzyme plus oxygen pre-treat with long dwell | The pick for set stains: the fact that you can leave it on for days is what makes it different from a normal pre-treat. |
| Dish soap alone | Surfactant degreasing | Best on fresh grease, every time, and it is step one here too. It does not work on set stains because it cannot break down oil that has been in the fabric a long time. |
| Oxygen bleach soak (the powder) | Bulk oxidizing soak | Best when a whole load needs treatment at once. It is weaker on a single grease spot, where a spray puts the cleaner right on the spot. |
The honest price comparison
A professional stain treatment runs $5 to $15 a garment, and cleaners often say a dryer-set stain may not come out. A $5 to $7 spray that handles a drawer of shirts across a year is the better bet for everyday clothes.
Where it falls short
The weaknesses below come from the product's own review record, the same record the recommendation rests on.
- It asks for days on the worst stains. Readers who need the shirt tonight will call that a failure of the product rather than of the timeline.
- Long dwell can fade weak or dark dyes; the test patch matters.
- On grease from bike chains or machine oil, results are only partial. That kind of grease needs a different product.

Questions people ask next
Is a dryer-set stain really not permanent?
Not usually. Dryer heat makes the stain harder to remove, but it does not make it permanent. Leaving a treatment on for a long time still reaches the oil. Expect good results on cooking grease, and partial results on industrial grease.
How long can I leave the spray on?
The label allows up to a week. In practice, one to three days handles most set food grease; re-wet the spot if it dries out, because the chemistry works while damp.
Warm or cold wash after treatment?
Use the warmest water the garment's care label allows, because warm water carries the loosened oil out of the fibers better. Follow the care label even if warmer water might help the stain.
Will it work on grass and blood too?
It is the same product the other guides on this site use: the grass-stain and blood-stain guides both use it for their product step, with their own preparation steps first.
