Cold-water washing won’t kill fungal infections
The researchers took samples from 81 socks worn by patients with tinea pedis, caused by the fungus Trichophyton rubrum, and washed them at 40°C and 60°C.

This compared to only 6% of socks washed at 60°C being positive for fungal cultures and all were caused by Aspergillus.
Trichophyton rubrum was found in four of the socks washed
