Try olive oil. I use that to get most things including weed off my hands. I assume you want the stain off and not a beetroot stain 'of' your hand
...Which may actually look quite artsy
I thought I might actually go for a full Turin Shroud of myself with beetroot juice.
I just tried a spud and the spud was turning purple so it must be taking some off.
I've also put 40ml of 17.5% H202 in two litres of water and washed hands in that which has made it fade quite a lot. I've thoroughly rinsed them after too.
I think I'll just have to wait for it to wear off.
Thanks for all the tips. My missus was very sympathetic and didn't find it at all funny.
I think Nick Cave and The Bad Seeds wrote a song about my issue but it's both my hands not just my right one lol
