Dingy underwear - how to get them sparkly again

[Grumpyoldblonde]

Hi there,
I expect this has been discussed before but I am between packing to go on holiday. Does anyone have a fool-proof method of turning undies back to white after they have gone that horrid chewing gum grey from the wash? I try to wash bras by hand to keep them white but obviously not possible with knickers, I have tried the in machine whitening sachets but they turn my things yellowy, any tips?
Thanks in advance, Grumpy

The best thing I found that took my now grey items back to sparkling White was a boil wash, Daz soap powder, and some white vanish. My boil wash is 95degrees so not really environmentally friendly but I don't do it often. And after the wash get them hung outside on a sunny day, let the sun help too !! Let me know how you get on. (On the bra front I just do them in a basin same method as above, obviously water not as hot!)

Glo-white on a 60 degree wash, use bio powder, not liquid

Sorry not replied, been on holiday! great tips thanks, I shall give them a go, I did think a hot wash would make it worse tbh, but if it works for you I shall try, thanks again

M&S whites wash is really good.

If stuff really dingy, soak them in a bucket of mild bleach solution before washing.
