Laundry advice

I would suggest, politely, that your husband uses an antiperspirant to lessen this problem.

A good deodorant?

I mix a paste of hydrogen peroxide, bicarb and washing up liquid. Spread it on area under arms. Leave for an hour then wash.

MrA used to get yellowing on white shirts and tennis tops caused by antiperspirant and sweat, and the mix used to get rid of both yellowing and residual smell.

I use the Tesco Oxy laundry stain remover spray. It froths up if there's a biological residue in the fabric, so you can see it working!
£1.50 for 500ml.

Plenty of tips. Use the cheapest first, they all work.

Soak in solution of Bicarbonate of Soda.

No need for expensive products.

I agree and I have sometimes made a paste of bicarbonate of soda if the 'stain' was particularly stubborn. Same paste can also be used on the underarm skin where there's often a build up of antiperspirant - sounds mad I know but it works! Jut rub into the dry skin before showering as normal.

Don’t use a tumble dryer, if you can line dry.
The bacteria multiplies in the heat.
You need to pre soak and wash at 60;;

Yes I would advise bicarb. Have done this myself on occasion with particularly stinky garments.

Hi, i had this problem with DHs tee shirts from the gym so as soon as he took them off I pre soaked them in an antibacterial laundry laundry cleanser with washing liquid. When I washed them I put a capful of the same antibacterial cleanser in the fabric softener section of the drawer. It seems to do the trick.
