Thanks everyone,
Had to ask in case I threw out over 100 posts then found out there was a simple foolproof way to restore them.
I like your idea Crash regarding the peroxide and UV, I made the missus a UV lamp for her nails and might try a couple of posts in a clipseal bag of peroxide under the lamp and see how it goes. I am sure she will have peroxide around here somewhere!
Here is a pic of the lamp I made using an old coffee tin.
