The short answer
Rub fresh white marks off dry with a cloth. For yellowing, lay the top flat, work a dilute white vinegar solution into the underarm with your fingers rather than a brush, leave it an hour, then wash cold and dry flat. Never use chlorine bleach on jersey with elastane in it, and never tumble dry it.
If it has just happened
Take it off and lay it flat rather than hanging it. Rub white deposit off dry with a folded cloth, supporting the fabric underneath with your other hand so you are not stretching the knit as you rub.
Heat can set this stain permanently
Do not use hot water, a tumble dryer, an iron or a steam cleaner until the mark has gone. Heat fixes this type of stain into the fibres and makes it far harder to shift.
Test on a hidden area first
Try any cleaner on a hidden part of the material first, such as a seam, an offcut, inside a hem or under a piece of furniture. Wait for it to dry and check for colour change before treating the visible mark.
Keep every source of heat away until it has gone
This includes the tumble dryer, the iron, a steamer, a hot wash and a radiator. Heat does two things to a deodorant mark at once: it drives the residue further into the material, and it speeds up the reaction between the aluminium salts and the proteins in sweat that produces the yellowing. Check the mark while the item is still wet, in daylight, before anything warm goes near it.
Never follow vinegar with bleach, or bleach with vinegar
Chlorine bleach and any acid release chlorine gas, and white vinegar is the standard treatment for this stain. Rinsing in between does not make it safe. Choose the acid route or leave bleach out of the house entirely for this job, which for a deodorant mark you should be doing anyway.
What you will need
- A clean dry cloth
- White vinegar What this is One part vinegar to four parts cool water.
Helpful but not essential
- Washing up liquid A drop, worked in with fingertips.
- A clean towel To dry the top flat on.
Fresh deodorant on jersey
Fresh transfer on a knit lifts off dry, but the fabric has to be supported while you do it.
-
Lay it flat and support the fabric
Put the top flat on a table with the underarm accessible. Hold the fabric from underneath with one hand so the knit is not being stretched by the rubbing.
-
Rub the deposit off dry
Use a folded dry cloth in short strokes in one direction. Do not wet it first, because the waxy carrier spreads into the loops and becomes far harder to reach.
-
Wash cool and dry flat
Wash at thirty degrees or cool, then reshape the top and dry it flat on a towel. Hanging a wet knit by the shoulders stretches it.
Dried deodorant on jersey
Yellowing at the underarm, or a stiff patch that has survived a wash.
-
Work a dilute vinegar solution in with your fingers
Mix one part white vinegar to four parts cool water. Wet the underarm with it and work it in with your fingertips only. No brush: bristles on wet jersey pull the loops.
-
Leave it to soak flat
Lay the top in a shallow bowl or tray so the underarm sits in the solution and the rest is supported, and leave it an hour. Keeping it flat stops the weight of the wet fabric distorting the knit.
-
Rinse and add a drop of detergent
Rinse in cool water, then work a drop of washing up liquid into the area to lift the waxy component the acid has loosened, and rinse again.
-
Wash cool and dry flat
Wash at thirty degrees, reshape, and dry flat on a towel away from a radiator. Check the underarm while it is damp.
Old or set in deodorant on jersey
A yellowed underarm that has already been through the dryer. Thin knits reach their limit quickly here.
-
Soak overnight, laid flat
One part white vinegar to four parts cool water in a shallow tray, with the top laid flat so the underarm sits in the solution and the rest is supported. Leave it overnight.
-
Rinse and follow with an enzyme soak
Rinse in cool water, then soak for four hours in cool water with biological detergent. Keep the garment supported and flat when you lift it in and out, because a wet knit tears under its own weight.
-
Work it with fingertips only
Press and release the area with your fingers rather than rubbing. On a set in mark on a knit, mechanical force does more damage to the fabric than it does to the build up.
-
Wash cool, dry flat, then stop
Wash at thirty degrees, reshape and dry flat. If the underarm is still yellow and stiff after this, it is staying: the remaining routes are oxidisers, and on a thin coloured knit they cost more than they return.
What not to use on jersey
-
The tumble dryer or an iron before the mark has gone
Heat and the aluminium compound together set the residue into the fibre and accelerate the yellowing reaction. Textile guidance is explicit that heat applied to a deodorant stain ruins most fabrics, and a mark that has been through a hot dryer is far harder to shift.
-
Wetting a fresh white mark before rubbing it
The white part is wax and salt sitting on the surface. Water dissolves the wax and carries it into the weave, turning something that would have brushed off into a stain that needs treating.
-
Chlorine bleach on anything containing elastane
Chlorine attacks elastane directly. The fibre does not fade, it fails, and the top goes baggy at the neck and cuffs permanently. Check the composition label before assuming a white jersey top can be bleached.
-
Brushing or scrubbing the wet knit
A knit has no fixed geometry. Bristles or hard rubbing pull loops through their neighbours and the fabric does not recover, leaving the underarm stretched and thin.
-
Hanging it wet
The weight of water in a knit pulls the shoulders and underarm out of shape as it dries. Dry it flat on a towel.
White compared with coloured jersey
Jersey is usually dyed as a knit and most colours are stable, but the underarm of a coloured jersey top is a bad place to discover otherwise. Test dilute vinegar on an inside seam and let it dry. Where the label shows elastane, chlorine bleach is excluded outright: it destroys the fibre rather than fading it, and the damage is immediate.
If the mark is still there
If a shadow survives the soak and a cold wash, repeat the soak overnight. Give the acid time rather than strength, because a stronger solution does not help and increases the dye risk.
Where two soaks change nothing, stop. Jersey tops are usually thin and the underarm is the part that wears out first, so further chemical work costs more in fabric life than it returns.
If the knit has gone stiff and slightly ridged at the underarm, that is aluminium build up in the yarn. It softens gradually over a number of washes rather than in one treatment, and it may never look new again.
When to stop and call someone
Not usually worth a professional, since most jersey is inexpensive relative to the cost of specialist cleaning. Take a jersey dress or a good quality top to a cleaner rather than experimenting if it is lined, structured or dry clean only.
Why deodorant behaves this way on jersey
The chemistry here is the same as on any cotton or viscose garment: surface wax and salt that lifts dry, and aluminium reacted with sweat protein that needs time in acid or enzyme.
The structure is what changes the handling. A knit is a lattice of loops with no fixed geometry, so force applied to a wet panel pulls loops through each other and the fabric does not return. That rules out the brushing and scrubbing that would be routine on a woven shirt, and it means the top has to be supported when it is lifted wet and dried flat rather than hung.
Where the blend includes elastane, which most jersey does, there is a second constraint. Chlorine attacks elastane directly and irreversibly, and heat above thirty degrees shortens its life every wash, which is why the dryer is excluded even once the mark has gone.
Do the usual suggestions work?
-
A dry cloth or a pair of tights
Yes, it works
On fresh white transfer this is the whole answer, and it is what manufacturers and dry cleaners both recommend first.
-
White vinegar soak
Sometimes
Genuinely useful on yellow build up, given an hour or more rather than a wipe. Does nothing worthwhile on a fresh white mark.
-
Bicarbonate of soda paste
Sometimes
Mildly alkaline and mildly abrasive, so it does some work on build up. Slower than an acid soak and it has to be rinsed out completely.
-
Chlorine bleach on the yellowing
No, it is risky
Reacts with the build up and darkens it, and weakens the fibre. This is the most common way a white shirt is finished off.
-
A soft brush on the mark
No, not recommended
Standard advice for woven shirts and wrong for a knit. Bristles distort the loops, and fingertips do the same job here.
Common questions
- How do I know if there is elastane in it?
The composition label inside the side seam. Anything listing elastane, spandex or Lycra, usually at two to five percent, counts. If there is no label, assume there is, since almost all modern jersey has some.
- The underarm has gone stiff but is not discoloured.
That is the waxy carrier and aluminium build up without the yellowing yet. A drop of washing up liquid worked in dry, left half an hour and washed out, deals with most of it, and it is a good sign you have caught it early.
Did this get the mark out?

Fabric care guide for stretch knits, Spandex by Yard
specialist
Specialist guidance for elastane blend knits: wash at thirty degrees or below and never above, never use bleach or chlorine based cleaners because chlorine destroys elastane immediately and irreversibly and fades synthetic dyes, and avoid the tumble dryer entirely including on a low heat setting because a single hot cycle causes permanent loss of elasticity.
