I've washed some polo shirts at 40° as per the label, on a wash cycle that takes close to two hours, but the armpit area is still smelly. I used Smol non bio.
Not sure if I will be able to scrub or soak to get the smell out. It's a mix of sweat and deodorant. Men's quite strong smelling spray deodorant if that makes a difference.
Would rather rewash than rag bag or cut up into cloths. Can anyone advise a product or had any success with bicarb or something? Thanks.
