Hmm. In my mixing, I have used tap water and not distilled -tried a nearby battery shop - but their distilled water was anything but.
I am seeing xtol turning deep blue. With usage. Working solution that is. Mixing it 1:3~
Also, is anyone experiencing that thesolution is getting evaporated with use -that happens even if stored in cool conditions, in shade? (relatively cool -current temps 27-8c in night and 35+c in daytime)
