What's that washing liquid that gets rid of stinky smells in my kit?

I have seen it on here, even if it's not in this topic. It's available on Amazon from what I can remember, I just can't blimmin remember what it's called.
My kit smells BO-ey literally as soon as I wear it again after washing, but it's only my tops, my bras don't. So I think they need fumigating but I don't generally tend to wash my kit on more than a 40 degree wash because of knackering the lycra. I thought normal washing powder might do the trick. Clearly not! And I'm starting to offend my own nostrils, never mind about anyone near me.

I'm not generally a sweaty/smelly person so it's not a lack of hygiene - promise!

Any suggestions, apart from burning said clothes, or wearing a nose clip, warmly welcomed

Have you tried using vinegar as a rinse? I chuck it in instead of fabric softener and find it great.

I think Halo sports wash has been mentioned a lot. I stick a couple of capfuls of zoflora disinfectant in the fabric softener bit of the machine when I wash stinky gym lit
