Hi have a 25L ultra pure distilling rig (called "Spirit maker" these days)... I was just thinking it might be time for a spring clean...
I normally just put it upside down in the still with a few cups of vinegar to clean the packing material, but I was wondering whether it might be time for a re-pack. I have had it for about 6 years now and have never replaced the packing... (still runs fine).
