Washing clothes & sweat stains?

Question

which clothes do you wash in cold water, hot/cold, and hot?

i know if you don't wash in hot water it's more eco-friendly. i usually keep my washer on hot/cold...

also, my dad is a mail carrier and wears white t's under his uniform shirt, and they have sweat stains. i was wondering how i can help him get rid of them? also, my brother has some sweat stains on the underarms of his shirts, so i'd like to help him out also :) some of his shirts have designs on them, so i haven't tried bleach on them bc i fear it will mess up the design, and if i just put it on the armpits i'm afraid the armpits will end up brighter than the rest of the shirt, lol.

thanks! :)

Answer 1

Put some lemon juice on them, it works very well with sweat stains and just plain stains also.

Answer 2

dark clothes wash in cold/cold

light clothes wash in warm/cold

and my dad has sweat stains to and they're there to stay

try cutting up the old shirts to make cleaning rags for around the house
