Zoflora cure?

[Imtoohot]

Some of my teenager son's shirts and t shirts have a sweaty armpit issue even after washing, will zoflora in the wash cure this? Or any other suggestions, I'd rather not throw them if poss.

White vinegar. Squirt a load on then wash as normal. Works first time. And it’s about 20p a bottle in Aldi.

Halo works brilliantly on sweaty armpits.

White vinegar - either squirt on, or soak clothes in it before washing. Cheap as chips, no nasties.

Get a bucket. Fill with hot water, add soda crystals and disinfectant (not stinky stuff). Mix well and add clothes, swirl them around a bit and leave them overnight.
Wring out
Wash on a medium wash with powder but without conditioner.

I use Dettol laundry detergent or the Tesco generic equivalent (seems just as good) on the feet of my stockings - works well even at low temp.
