If you have socks that are severely infected with tinea/athlete’s foot, what is the best laundry product to soak/wash them in? How much do I need to use? I can guarantee you that normal washing powder does NOT get rid of the problem. Whatever product or ingredient you recommend would need to have a "sledge hammer" effect on the tinea, as I’m really facing the mother-of-all-battles here. Also, hot water and/ or bleach are not an option here.
It’s not me that has the severe tinea problem, rather it’s my housemate, and the problem is beyond belief. I’ve said to a few people I know that his socks are undisputable proof there’s extraterrestrial life already on earth. He’s started using antifungal foot powder designed to kill tinea, and it’s made a huge difference already. Despite that, I need a laundry product as well, and I want to make this is as cost effective as possible.
