We’ve had an email from Nina:

What can I do with leftover pickled beetroot vinegar? We did the pickling ourselves in July and it seems a waste to throw the vinegar down the drain just two months later because we’ve eaten the beetroots – but we can’t use it for cleaning because it would dye everything pink!

Man, I love vinegar. Is there anything more delicious and versatile? But I agree the pink staining thing could be a bit of a problem here.

There are possible some cleaning things it could do where a pink stain or whatever wouldn’t be a problem – like removing rust from metals before painting – and studies have shown its worth as a herbicide.

Any other suggestions?
