I've seen a friend boil teatowels in bleach to get them truly clean. Does anyone know
-how much bleach to use?
-how long to boil?
-whether I need to do this in a pan I won't be cooking food in again, because bleach is a poison?
Also, does anyone know a good way of removing accumulated deodorant stains from the armpits of shirts? No matter how many times I wash certain shirts, the deodorant stains stay. I wear the shirt and it stays fresh for about an hour and then the old deodorant starts to smell, and it's a bit sour.
