Making grey nappies white again?

[Rootvegetables]

I used bum genius flips with my ds and liked using cloth but am pregnant now and hoping to get them all out again soon but know they were pretty grey when I put them in the loft, how can I make them lovely and white again?

Not a voice of experience here by any stretch, but I know some people will put Biotex in with the nappies in the wash which doesn't seem to cause any problems (as a short term/one off thing, no idea about regularly), it's a bleach-free stain remover. If you have outside space hang outdoors in sunlight. Apparently leaving them out overnight in cold/frosty weather gets them very bright too (from the cold? The moonlight? No idea!).

Or you could dye them. I, ahem, accidentally dyed half of my Flip stay dry and organic night inserts a few weeks ago by throwing a very bright deep turquoise towel in the wash They look rather good all aqua!

What are they made of? I dyed lots of cotton nappies, bamboo didn't take though!

Is it just the inserts? if so wouldn't bother, nobody sees that bit :) other than that UV light - doesn't even need to be sun, or outside, can be just hung in the window.
