Protocol
Method steps
- Read the care label Find the wash tub, hand-wash and dry-cleaning symbols. "Dryclean Only" or a crossed-out wash tub means the suit is not washed at home.
- Spot-treat marks first Dab a mark with a clean, slightly damp undyed cloth and a spritz of stain remover or mild detergent, and never scrub. If the dry-cleaning circle is crossed out, skip stain removers that contain solvents.
- Test the detergent Try the detergent on an inconspicuous area before washing; some fabrics cannot be cleaned with water. For a new-wool suit, use a wool detergent.
- Wash within the label's limit With a hand-wash symbol or Hand Wash Only, wash by hand only. With a numbered wash tub, machine wash no hotter than that number; bugatti's suit programme uses a high water level, a spin below 600 rpm and 30 °C at most. Wool trousers with a Woolmark Machine Washable label go on the wool setting instead.
- After a hand wash, rinse and squeeze Rinse several times in clear water, then wrap the suit in a terry towel and squeeze the water out carefully. Do not wring it.
- Hang to dry, never tumble dry Hang the jacket on a hanger with wide curved ends so the shoulder pads keep their shape, and dry the trousers lying on a terry towel on a clothes horse.
- Finish with steam Use a steamer rather than an iron unless the label allows ironing. Cotton and linen suits need ironing to remove creases; for wool, steam ironing is enough.
How to wash a suit starts with the care label. “Dryclean Only” or a crossed-out wash tub means no washing; follow the label’s dry-cleaning instruction instead. A hand-wash symbol allows washing by hand, a numbered wash tub allows the machine up to that number, and tumble drying is not suitable for suits.
Pick the route: label first, then fibre
Find your label wording or symbol in the first column, then your fibre; the third column is the route, the fourth is the method or limit that goes with it.
| Label shows | Fibre | Route | Method or limit |
|---|---|---|---|
| "Dryclean Only" in words | Any | Dry clean | Never washed at home: the words warn that the garment can't be washed |
| Crossed-out wash tub | Any | Do not wash | The article must not be washed |
| A dry-cleaning instruction and no wash symbol | Any | Dry clean | The label gives no washing method to follow |
| "For best results, dryclean" | Any | Wash or dry clean | Washable without damage; dry cleaning may be better for appearance and durability |
| Crossed-out dry-cleaning circle | Any | No dry cleaning | No stain removers that contain solvents either |
| Hand-wash symbol or "Hand Wash Only" | Wool | Hand wash | Lukewarm water at about 30 °C, mild detergent, 10-minute soak, rinse lukewarm then cold |
| Woolmark Machine Washable | Wool trousers | Machine wash | Wool setting, usually gentle action at 40 °C |
| Numbered wash tub | Polyester, cotton or a blend | Machine wash | Never above the tub number; bugatti's programme: high water level, spin below 600 rpm, 30 °C maximum |
| Numbered wash tub | Linen | Machine wash | Delicate programme at 30 °C; no heavy wringing |
| A wash symbol and a dry-cleaning circle that is not crossed out | Acetate lining | Dry cleaning preferred for acetate | If washed, squeeze gently by hand in lukewarm water with mild suds |
| Between cleans | Wool trousers | Steam-and-air refresh | Brush lightly, then hang in a steamy bathroom |
The US Care Labeling Rule explains the third row: an item that can be both washed and dry-cleaned needs only one of those instructions on its label, so a dry-clean-only symbol neither proves nor rules out washing. It just gives you no washing method to follow, which is why the table routes it to a dry cleaner. The wool rows come from The Woolmark Company (external link), the linen row from the flax-linen industry body (external link), and the acetate row from University of Georgia Extension (external link).
Reading the symbols on a suit label
The symbols below are the international care symbols that GINETEX (external link) documents, plus the one label wording the US rule defines. Together they decide the route.
Do not wash 
Dry clean 
Do not dry clean 
Hand wash 
Machine wash, 30 °C maximum - Crossed-out wash tub. The article must not be washed.
- Numbered wash tub. The number is the maximum washing temperature in degrees Celsius, which must not be exceeded.
- Hand-wash symbol. GINETEX has two: hand wash at ambient temperature, in water at around 20 to 30 °C, and hand wash at a maximum of 40 °C.
- Crossed-out dry-cleaning circle. No professional dry cleaning, and no stain removers that contain solvents.
- The words “Dryclean Only”. Under the US Care Labeling Rule (external link), they warn that the garment can’t be washed.
Select the symbols on the suit’s label and the decoder returns what each one allows and forbids, before any water touches the jacket.
Decode the suit labelStep by step: washing a suit the label allows
These steps apply only when the label allows washing: a wash tub, a hand-wash symbol or wording such as Hand Wash Only.
- Read the care label. Find the wash tub, hand-wash and dry-cleaning symbols. “Dryclean Only” or a crossed-out wash tub means the suit is not washed at home.
- Spot-treat marks first. Dab a mark with a clean, slightly damp undyed cloth and a spritz of stain remover or mild detergent, and never scrub. If the dry-cleaning circle is crossed out, skip stain removers that contain solvents.
- Test the detergent. Try the detergent on an inconspicuous area before washing; some fabrics cannot be cleaned with water. For a new-wool suit, use a wool detergent↗.
- Wash within the label’s limit. With a hand-wash symbol or Hand Wash Only, wash by hand only. With a numbered wash tub, machine wash no hotter than that number; bugatti’s suit programme uses a high water level, a spin below 600 rpm and 30 °C at most. Wool trousers with a Woolmark Machine Washable label go on the wool setting instead.
- After a hand wash, rinse and squeeze. Rinse several times in clear water, then wrap the suit in a terry towel and squeeze the water out carefully. Do not wring it.
- Hang to dry, never tumble dry. Hang the jacket on a hanger with wide curved ends so the shoulder pads keep their shape, and dry the trousers lying on a terry towel on a clothes horse.
- Finish with steam. Use a steamer rather than an iron unless the label allows ironing. Cotton and linen suits need ironing to remove creases; for wool, steam ironing is enough.
The machine programme in step 4 is the menswear maker bugatti’s guidance (external link) for suits its label allows; it also says a wool detergent contains no enzymes that can attack the wool, and that tumble drying is not suitable for suits and trousers. The ironing rule in step 7 comes from Suitsupply (external link) and the fibre split from Canali (external link).
Three fibre notes sit on top of those steps:
- Wool. Woolmark says to turn wool trousers inside out before washing them, and that tailored suit trousers or jackets can be hung on a hanger and dried out of direct sunlight (external link). The knitwear method, with its felting rules, is in the wool sweater guide.
- Polyester. If it needs pressing, set the iron to a low temperature and use steam. The fibre’s own method is in the polyester washing guide.
- Linen. Avoid heavy wringing, which could cause marked folds and damage the fabric texture. The full method is in the linen washing guide.
Hand washing a suit, in detail
When the label shows a hand-wash symbol or says Hand Wash Only, bugatti’s procedure is to fill a small tub with lukewarm water, dissolve the wool detergent completely, then soak the suit, avoiding a prolonged soak. For wool, Woolmark puts the water at about 30 °C and the soak at 10 minutes, then rinses first in lukewarm and finally in cold water. Before hanging, bugatti pulls the jacket and trousers into shape and closes all the buttons, to avoid creases.
Four routes, and the downside each source names
No route is free. Each row below pairs a route with the label that allows it and the downside a source attaches to it.
| Route | Allowed when the label shows | Downside a source names |
|---|---|---|
| Machine wash | A numbered wash tub | Canali says machine washing is definitely to be avoided for its suits |
| Hand wash | A hand-wash symbol or Hand Wash Only | Canali warns that repeated hand washing risks ruining the fibres |
| Dry clean | A dry-cleaning instruction | Canali: the solvents can corrode and damage fabrics over time; a fused jacket can bubble |
| Steam-and-air refresh | Between cleans, for wool suit trousers (Woolmark's scope) | It removes creases; the source does not present it as cleaning |
What the jacket’s construction changes
Inside the jacket, the interlining and the lining carry risks of their own. They do not change the route the label sets; they are what to watch for after any cleaning.
| Jacket build | What it is | Risk to know |
|---|---|---|
| Fused interlining | Adhesive melted under heat and pressure laminates the interlining to the outer fabric | A poor bond makes bubbling (delamination) likely during cleaning and/or finishing |
| Fused interlining, dry cleaned | The same bond in a solvent process | In one analysed case, adhesive unsuited to perchloroethylene on a standard process became molten, most likely during drying |
| Sewn interlining | Stitched between the outer fabric and the lining without adhesive, heat or pressure | Not a sign the suit can be washed: the label still decides |
| Acetate lining | A lining fibre that melts at low heat | Press it while damp, on the wrong side, with the iron at the lowest setting |
The fused and sewn rows come from a trade analysis of interlinings (external link) written for professional cleaners, which notes that fused interlinings are typical of suit jackets. The acetate row comes from University of Georgia Extension (external link).
Refresh between cleans, and how often to dry clean
Wool trousers generally won’t need washing after every wear, because wool is stain and odour resistant. For creases, Woolmark’s route is to brush wool suit trousers lightly and hang them in a steamy bathroom, which gives them a quick refresh and removes creases.
Suitsupply adds three habits for the days between wears. Resting a suit for 24–48 hours before wearing it again reduces the need to visit the dry cleaner. It recommends a broad wooden hanger, ideally cedar, and never a flimsy plastic hanger for jackets. And it names a genuine boar-hair clothes brush as the gentle way to keep the fabric free of unwanted particulates.
Two suit makers put a number on dry cleaning:
| Maker | How often | Reason given |
|---|---|---|
| Suitsupply | No more than three times a year | Cleaning after every wear is unnecessary and wears the fabric out more quickly |
| Canali | A couple of times a year at most | The solvents can corrode and damage fabrics over time |
Next: the method for your fibre
If the label allows water, open the guide for the suit’s main fibre: wool, polyester, linen or cotton. For drying rules by fibre, see what can go in the tumble dryer, and for any symbol not covered here, the care-symbol glossary.
