Could anyone tell me how and where to store litmus paper. Our red and blue both look red! The blue has turned a real red/pink colour - not even a blue tinge.
I'm not sure of the self life of litmus paper - but maybe that is the problem.
Would appreciate some advice.
We store ours in the little black containers you buy rolls of photographic film in. No problems as a result and they last for years with no discolouration.

If you ask at you local photo shop for the canisters,they usually have a stash of them, if not ask them to save you a few, I did this and ended up with a shopping bag full, more than enough for what I needed them for.

Hi Di,
I revitalise the blue litmus by holding the booklets over an open bottle of conc. ammonia in the fume cupboard. Just fan them a little to let the fumes have an effect. Blue litmus turns from pink to blue again.

I store some litmus paper in a jar with a few drops of ammonia. Put something between the paper and the ammonia so only the fumes get to the paper. Works ok.
