I tried white vinegar twice as suggested but it proved useless.

i have no idea how these extensive yellow stains appear on my clothes which i don't wear for more than half a year. They are not from food or drink stains, and they have no smell at all.

it is so strange this is the only white clothes i found with yellow stains, however other white clothes maintain pure white for years.

If i bleach this clothes, is it bad for my skin ? it is a summer clothes.

Thanks.

It seems that it's proteins that aren't washed out and they degrade in storage, or even, possibly, when you handle the clean clothes with sweaty hands and put them away. A quick scout suggests something that releases hydrogen peroxide to sort it. Oxiclean is one commercial product that seems to be quite commonly available that releases peroxide.

hydrogen peroxide is widely used in cleansing products and tooth whitening.

If i can't get Oxiclean, are other products available ? or does toothpaste contain hydrogen peroxide ?

What's wrong with ordinary bleach?

I've heard aluminum in some antiperspirants reacts with the salt in your sweat causing yellow stains. I agree with John Cuthber though, bleach will remove the stains. Rinse well, you should be fine.

She can try both.

She should. One on each underarm. And share the results.

underarms have no yellow stains at all....odd ?

Wash the bleach away before wearing.

Some people can't work with the gases.

Chorine

gases?

 

Some find it hard to use chlorine at all because of the gas, even if you can rinse the clothing thoroughly.

 

It sounds like OxyClean will be best. StringJunky ftw.

 

Stains on the back suggest you leaned against something that had the yellow staining agent. Is it on all your white clothes? In the same place?

no, the yellow stains are ONLY on this white clothes( some on cuffs.), others remain as white as before.

it is very strange.

How to use gas chlorine to bleach clothes ? it is dangerous !

No, we're just talking about the smell of the bleach. Some people don't like working with chlorine bleach at all because of that.

"This white clothes"

 

"others remain as white as before"

 

If I understand you correctly, only one white garment (or very few white garments) are stained this way, while other white garments aren't stained. Is this correct?

 

If this garment(s) has been washed, perhaps it was a darker brown or yellow stain originally, and is now a more faded yellow?

some washing-powder companies hype that their product can whiten the clothes and make them look whiter than before, what ingredients do they have ?

yes, you are correct, only this one is stained yellow and it was white before. Any stain on white clothes would be very obvious and easy to spot.

this clothes was washed by hand and put into my wardrobe for more than 6 months before i found it yellow stained.

it must have had some mysterious chemical reactions during this duration.

Before we jump to "mysterious chemical reactions", is there a possibility there is something in the wardrobe that this garment might have brushed up against to give it stains after you had washed it? Was this garment hanging in between other garments, or was it against the sides/back?

It's unusual for a molecule as small as hypochlorite to produce an allergic reaction- it's not big enough to be recognised by the immune system.

There are, of course, other hypersensitivity reactions- not least psychosomatic ones.

I only put soaps in the wardrobe and it was hanging in between other clothes which are not yellow.

If the garment was washed and put in the wardrobe clean, but came out stained, either something from the wardrobe stained it or something not visible is happening, like a possible reaction. It could also be that the garment is old, and the white dyes are degrading, making it seem stained.

Some sort of mold?

If the garment is in good shape physically, there are whitewash additives for white-only laundry that will probably restore it. I've never used them, but a flat I rented in Paris had some for black clothes. Your whites must be very white, your blacks very black. I think it's actually a law in France.

Cotton is white- it doesn't need a "white dye".
