Do pee stains come out of gray underwear?

Question

Im serious. I went to a friend's and I forgot to go before leaving. I peed in my pants on the way home. Im wondering if I need to wash it right now or if it can dry and be washed later. Im worried if the wet dries in, ill have a stain and in PE, when im changing, kids will say "Hey look! Jason has a piss stain!" Will my underpants stain if I let the pee dry then wash it tommorow? If you need sepcifics, they are boxerbriefs, made 95% coton, 5% spandex and are gray.

Answer 1

If you are worred, you could rinse it well with hand soap (just any soap you happen to have) squeeze the water out, throw it over the edge of your tub or shower and then when you take your wash to the laundry, just add it to your load.

Answer 2

just rinse them now and than wash them when you do the rest of your cloths, it won't stain
