How can I get my favourite bra white again?

[MistressMary]

It had a collision with something pink and now it looks nasty dull greyinsh/pink colour and like old tat.
Any ideas?

is it cotton or nylon? If nylon, sometimes net curtain whitener works, if cotton try that oxy whitening stuff.

dye stripper!

Cheers.
Off to town to get some supplies then.
