cotton and polyester puma sock I washed with some pooped underwear, so I don’t know if this sock looks brownish due to fecal matter.
I used a cold cycle and abundant detergent. Every other undie looks fine.
I don’t know if I should leave the piece to rinse in a cold water bucket with some detergent and wash again.
Just one sock of the pair is discolored? Maybe try washing the just the other sock with some poopy underwear to make it browner so the pair matches again.
