Chef coats take more abuse than almost anything else in a wardrobe, and they take it every shift. Heat from a range, oil in the air, splashes that land and dry in seconds, and salt from a long hot day, all going into heavy white twill expected to look presentable by morning. Most are ruined by the wash rather than by the work.
What the garment is built from
A chef coat is usually heavy cotton twill or a cotton and polyester blend, cut double breasted so the front panel can be swapped over to hide a mark.
The weight is deliberate. Thick twill gives a layer between a splash and skin, which is why the fabric is denser than a shirt and why it holds on to whatever lands on it.
The blend matters more than anything else on the label. Cotton takes high temperatures and releases oil reasonably well. Polyester is the opposite. It tolerates less heat and it grips oil tightly, because oil and polyester have a genuine affinity for each other.
That is why a poly blend coat can come out of a wash looking clean and then show a shadow of every old splash the moment it is under a bright light.
Double breasted fronts also mean two layers of fabric across the chest, which is the slowest part of the garment to wet through and the slowest part to dry.
Work shirts worn in the same setting behave exactly like chef coats do. Anything in a heavy weave worn near heat and oil has the same three problems.
Why chef coats come out still marked
Because the marks are mostly oil, and oil does not dissolve in water at any temperature.
Detergent works on oil by surrounding it and lifting it into the water, which needs three things together. Enough detergent, enough heat, and enough water volume to carry it away.
Take away any one of those and the oil moves a short distance and settles back into the fabric, usually as a broad dull patch rather than the original spot.
A packed drum removes two of them at once, which is why a machine crammed with heavy coats is the most common reason they come out disappointing.
Cold water is the other usual culprit. Kitchen fats are solid at room temperature, and a cold wash never gets them to a state the detergent can lift.
And a single wash will not always finish the job on an old mark. A spot that has been through a dryer is a different problem, covered further down.
Oil, and the thing that makes it permanent
The single rule that saves more chef coats than anything else is this. Never put one in a dryer while a mark is still visible.
Heat oxidises oil that is still in the fibre, and oxidised oil changes chemically. It goes from a stain that detergent can lift to a yellow brown discolouration bonded to the fibre itself.
That is why the mark that was faint on Monday is permanent by Friday, and why people think the wash caused it. The dryer did.
So check the whole front under good light before anything goes near heat, and put anything still showing back through.
Pre treating is worth the two minutes. Work a small amount of liquid detergent directly into the dry spot with a fingertip or a soft brush, going from the outside of the mark inwards, and leave it fifteen minutes before washing.
Do the treating while the fabric is dry rather than wet. Water in the fibre gets in the way of the detergent reaching the oil.
For old marks that have already been through heat, repeated treatment and washing will lighten them and rarely removes them completely. It is worth knowing that before spending an evening on it.
Whites that have gone grey or dull
Two separate things turn white chef coats off colour, and they need different answers.
Grey is redeposited soil. It happens when there is not enough water or not enough detergent to hold what came off the fabric, so it settles back across the whole garment evenly. The answer is a fuller water volume, a smaller load, and the correct detergent dose rather than a bigger one.
Yellow is usually oil that has been through heat, or it is the polyester itself reacting to chlorine bleach.
Chlorine bleach on a poly blend is a mistake people make once. It yellows the polyester permanently and it weakens cotton fibres at the same time, so the coat both looks worse and wears out sooner.
Use an oxygen based whitener instead, dissolved in warm water before the garment goes in, and give it a long soak rather than a short hot wash.
Wash whites away from anything that sheds lint. A load of white coats run with towels picks up fibre that reads as dullness even when the coat is clean.
And wash them separately from heavily soiled dark work clothes, which is the fastest route to grey there is.
Buttons, studs and knots
The fastenings are the part that fails first, and they are the reason a coat gets retired while the fabric is still fine.
Cloth knot buttons crush flat under a heavy load and fray at the stem. Fasten them before washing so they sit in a closed front rather than catching on the drum.
Metal studs are usually removable, and the ones that are should come out. A stud left in goes through a wash fine and then leaves a rust coloured ring after a few months.
Plastic buttons crack under heat more than under agitation, which is another argument for taking the drying temperature down.
Turn the coat inside out if the buttons are fixed. It puts the fabric against the drum instead of the hardware.
A mesh bag is worth using for anything with delicate fastenings, and it costs you nothing in cleaning because the water still moves through it freely.
Drying, pressing and getting the shape back
Take the drying temperature down and take the coat out slightly damp.
Heavy twill holds a lot of water and the temptation is to run it long and hot, which shrinks cotton, hardens any remaining oil and bakes creases into the double front.
Hang it on a proper hanger while it is still damp and pull the front panels straight with your hands. Most of the pressing does itself.
If it needs an iron, use a hot iron on a cotton coat and a much cooler one on a blend, because polyester glazes and goes shiny under heat that cotton tolerates easily.
Press the double front from the inside out, and do the collar last so it does not get crushed again by everything after it.
Light starch on cotton helps a coat stay crisp through a shift and makes the next wash easier, because splashes sit on the starch rather than going into the fibre. Skip it on blends, where it flakes.
Hang chef coats rather than folding them. Folded heavy twill holds the crease, and you spend the next morning dealing with it.
Common questions about chef coats
What temperature should chef coats be washed at?
As warm as the label allows, and warm genuinely matters here because kitchen fat is solid at room temperature. Pure cotton coats usually take a hot wash without trouble. Blends are limited by the polyester, so check the label, and compensate with pre treating and a longer cycle rather than by pushing the heat past what it says.
Can I use bleach on a white coat?
Not chlorine bleach on anything with polyester in it, because it yellows the fibre permanently and there is no way back from that. An oxygen based whitener dissolved in warm water and given a long soak is the right tool, and it is gentler on the cotton as well.
Why does a grease spot come back after washing?
It was never fully removed. The detergent lifted part of the oil and the rest spread out into the surrounding fabric, where it was invisible while damp and reappeared as the coat dried. Treat the spot directly on dry fabric, wash in a loose load with plenty of water, and check it before it goes anywhere near heat.
How many can I wash at once?
Fewer than you think. Heavy twill soaks up a lot of water and a drum that looks half full when dry is effectively full once it is wet. Grease needs room and water to move away from the fabric, so a loose load in a large drum does a better job than two tight loads in a small one.
The Mesa part
Heat is the local factor and it stacks on top of the heat the job already brings. Somebody working near a range through a long Arizona summer is dealing with kitchen temperatures and outdoor temperatures at once, and the garment absorbs the result of both.
That shows up as salt. Sweat leaves mineral behind as it dries, and salt accumulates in collars, cuffs and under the arms as pale stiff patches that ordinary washing at low temperature does not shift. A cool water soak before the wash dissolves it, and it wants doing before heat has a chance to set anything on top of it.
Hard water makes the whites harder to keep white. Water here carries a lot of mineral, and mineral combines with soap to leave a film across fabric that reads as grey no matter how much detergent goes in. Half a cup of washing soda in the wash handles the hardness itself, and using less detergent rather than more is the counterintuitive part that works.
Dry air is the compensation. Heavy twill is slow to dry almost everywhere else, and here a coat hung on a hanger with air moving past it finishes in a few hours without needing a long hot tumble. Keep it out of direct sun, which fades and weakens the fibre faster than most people expect, and shade does the job nearly as quickly.
Where heavy work clothes get proper water
Kitchen oil comes out with water volume and room to move, and neither of those exists in a packed home drum.
The machines at our self-service laundry on East Broadway Road move far more water through a cycle than a home unit and have drums big enough that a stack of heavy twill can tumble loosely, which is the condition oil actually needs to leave the fabric.
Our machines and the store are cleaned daily.
Our wash-dry-fold service covers the everyday laundry.

The short version
Chef coats fail from oil rather than from ordinary dirt, and oil needs warmth, enough detergent and enough water volume all at once. Treat visible marks on dry fabric with liquid detergent worked in from the outside inwards, leave it fifteen minutes, then wash as warm as the label allows in a loose load. Never put a coat in a dryer with a mark still showing, because heat oxidises oil and turns a removable stain into a permanent yellow one. Use an oxygen whitener rather than chlorine bleach on any blend, keep whites away from lint and from dark work clothes, and hang the coat damp instead of drying it hard.
