I have been buying fish tan liquid, it works great and i can leave the skins soaking for months with excellent results. However I'm sure as most i would like to make my own. I've read a lot of different combos. I don't want to ruin the skins I have with a bunch of trial and error. Honestly the liquid i buy smells partly like alcohol water mix. Could this just be what i use? Half and half? I've read borax and water only.
