Do you guys use a dental tool or similar to remove and clean/lube all the seals on your corny kegs? The ones on the post are a little tough to get off and I feel like I damage them a little when I remove them (I've been using a butter knife but maybe use a dental tool next time). Should I just leave them on and wash the posts as a whole / lube the exposed part or should I be fully disassembling them? Thanks
