Grey bras

Sorry but that’s why I never buy white bras, only nude. They go under everything.

Why don’t you try dyeing them? I doubt you will ever get them sparkly white

Oxygen bleach for whites? I've given up buying white too. I've sewn folded ribbon over the straps of some old favourite ones. At home, I never wear them, though, far more comfy without.

I mostly buy black and coloured bras as white ones always go grey. For summer I buy a new white one to wear under white tops, and when it starts to go grey, I “use it up” in winter under clothes where it’s not seen?

I always buy either nude or black. Try dyeing them. White ones look nice when new but it doesn't last.

They don't last forever and lose their elasticity so I would gradually replace them. I also only go for skin tone as white tends to stand out, even under white!

Black and nude are perfect for everything and as others say they don't discolour. I buy matching briefs to go with them too so I don't have to worry about matching undies anymore.

Thanks for all the replies, but not much help in recovering my old grey ones. I do wear black and nude as well, but really like the nice crisp whiteness of a white bra, and I find them best under white strappy tops,

I dyed an old bra purple once and it was amazing how it turned out. The different fabrics in it turned different shades of the colour. An average every day bra ended up looking like something from Rigby and Peller. I also dyed knickers to match so had an amazingly pretty set for the cost of a Dylon dye!

You could try the product that is meant to keep net curtains white.

You used to be able to buy a product called 'Glow-white' which was good for getting children's acrylic nylon socks sparkly white. Since my children have long since grown out of white socks, l have never looked to buy any, but it was good for brightening up other things like net curtains and lace tablecloths, probably Bras and undies too if l had ever tried it, but like a lot of posters on here, l tried to stick to buying coloured underwear and night wear wherever possible.

I have a friend who dyed all her old stuff pink. It looked good.

I remember being told by a woman, whose mother worked in a lingerie factory, that the whiteness is added to the material so, once it is washed out, it has gone. Her recommendation was to wash white bras in gentle detergent and cold water. Can’t say if it works: mine were already going grey but, I am seriously considering investing in some Dyson.

I have black, pink and nude bras. I gave up buying white ones some years ago.
I never found a way to whiten the greying white ones that I owned.
Sorry that I don't have a solution.

An old trick from years ago is to soak your old grey bras in a super strong bowl of tea and fingers crossed you should have a tea coloured (nude) bra. Worth a try & won't cost more than a couple of tea bags.

If you wash whites only with other whites at 40 - 50 degrees and use Daz powder you'll keep your bras and briefs a good white for at least a year. After that length of time the elastic tends to sag. Hope this helps.

I put all my light colour underwear together in the washing machine use the cloths that catch the colour and use Persil colour care powder, and sometimes add the vanish oxygen white powder very little, they seem to keep their colour,

Buy new ones

If you die them the different materials in the bra will end up different shades, Might be interesting.

I think, if you don't feel you like them grey, you've nothing to lose by trying to dye them.

I have one white bra in case I wear something pale (a rare event) but mostly I wear black ones. Much easier.

I save up white tee shirts, underwear etc until I have enough for a totally white wash. Usually once a week when sheets and pillowcases need washing. Don’t have a problem with greying that way.
Did try the net curtain whitener that Dylon do when revitalising a 34 year old christening dress made from my 49 year old wedding dress. That worked quite well, but it was still not the sparkling white of new fabric.

If they are cotton you could try soaking them in a bleach solution before washing.

Have you tried a tablespoonful of Napisan in with the white wash?
I was told that by someone who wore a lot of white, and always looked bandbox fresh.

As mentioned by a pp I dyed some old bras using black tea. This was over 40 years ago. It worked quite well.

Around that time I have birth and was in the hospital. I asked my husband to bring me in another bra. That night he walked in with this tan coloured bra in his hand. I could see it shining from the end of the ward. It wasn't meant for public viewing!!
