Good idea. I've used the same principle on the rim of WCs. 10% citric
acid
solution is much stronger than vinegar and just as easy to handle.

I use brick acid. A bit stronger still...
And dangerous to handle..... and a bloody nuisance to store. Sulphamic is
the best of both worlds, but you can't just nip round the chemist's to buy
it. Citric was 69 pence for 100gms last time I looked.

If you have a left over lemon from a meal, there's enough citric acid in it
to clean some lime scale.
