I've been using a DIY storage solution after cleaning my pH probe with Hanna pH probe cleaning solution, as Hanna state to soak in cleaning solution for an hour to recharge the electrode.
My DIY is a 3M solution of KCl which I mix 50/50 with a Hanna ph4 buffer.
Recently I read that perhaps a better solution is to take 100ml of ph4 buffer and dissolve 10g of KCl into it.
Does it really matter, and if so which would be better for probe longevity?
