ah-soy Posted November 13, 2007 Share Posted November 13, 2007 I've been making balms and butters for a few years and packaging in different containers (mostly PET) but recently packaged some in aluminum screw top tins for testing...I love the look and the recycle angle (although they do dent easily) BUT noticed as I reached the bottom of the tins and rub to get the last of the product that a greyish residue comes off the tins with the balms. I know I need to research this further and find out what this is, but wondering if anyone else uses these and has experienced this???
