Thread: Leder skin tanning kit

Hey Team,

I have a few questions regarding the leder tanning kit. August last year I tanned up a nice sika hind skin using the kit and mixed up a full brew of the formula, 35 litres I think. I have kept the leftover liquid solution in a big bin since and now have a fallow skin to do. The kit says it can tan up to 6kg's of skins, I'm assuming the sika skin wouldn't of been 6 kg ( should've weighed it). Regardless, does anyone know if the tanning solution expires once mixed up? Or should it be sweet? If not, how's everyone disposing of the tanning solution? Wanting to to the right thing and not just tip it down the drain. The manufacturer suggested putting it in rubbish bags then into a wheelie bin... can't see that working very well somehow. Cheers.
