Why does white clothing come out of the wash with stains they didnt go in with?

I don't understand what I am doing wrong. I will have a clean new white T-shirts and when I take them to the laundromat and they are finished washing they have oil looking stains on them that they didn't have before they went in. The washers are not visibly dirty either, does anyone know why this happens and how to prevent it? How to get my whites, white again and how to stop deodorant from ruining the under arms of my shirts. I used clear name brands but am not choosy and when the sweat and deodorant combine, they stain my shirts underarms and cannot be washed out!!! HELP!! Why does white clothing come out of the wash with stains they didnt go in with?
Use white vinegar for the arm pit stains. Pour it straight on and then wash.


It looks like someone is washing greasy stuff before you get to the laundromat. Might be an idea to wash a load of towels in really hot water in the machine you want to wash your tshirts in. That way the grease will be cleaned out before you use. You could put a can of coke in with the towels and the coke will clean any grease there is in the machine. You could also try putting the can of coke in with your tshirts when you wash them. You can't beat coke for removing grease and odor.Why does white clothing come out of the wash with stains they didnt go in with?
First you should apply deodorant before retiring to bed this way the deodorant has a chance to dry into your skin and therefore will not leave that white mess you are experiencing on your shirts, and to remove this white mess from your shirts you should use Baking Soda and a little Dishwashing Liquid and make a paste then scrub with an old Toothbrush and wait for about an hour then toss into your washer with the hottest water your shirts can handle and then cold rinse Or you can:Remove deodorant stains . Baby wipes remove the white marks left behind by most deodorants. Just wipe and you鈥檙e on your way. Good Luck !
As far as invisible stains go, I know if I've spilled milk on my shirt and put it in the wash it'll come out as a stain.


Always take a damp cloth to any thing you soiled as soon as it happens. It's better for your clothes (and for the environment too.)
The oil stains might be coming from other clothes in the load. Make sure you pretreat everything ahead of time %26amp; if you've worn things to cook, or work in an environment where you come into contact with oil, wash those things separately.
If the water isn't at least 120 degrees. You will have a hard time removing. Touch glass to test temperature. Let the laundromat people know or go elsewhere.
If you use fabric softener and it touches the clothes before it is diluted it can leave a yellowish light brown stain.
