Interesting - none of our chamois' are white
They are mostly a fawn/tan colour

We do have a few of the newer red and blue ones too.

If you are worried about the stains, then soak your shorts in a nappy cleaner (I use napisan - dunno what the various brand names are round the world)

I don't usually use this, and just wash in washing machine... but on occasion when I have period overflow (yes, had a smidgen happen last time despite my moon cup -it was my heaviest day, a looong ride over serious hills demanding serious exhertion -sp?) or alot of vaginal discharge.

But stains should only really be seen by you (I hang shorts on the line with the but side facing the centre of the washing line) and providing you have cleaned them well enough, then the stains will just be colour
