I do not use a crock pot on stove to melt my wax I got this from the wife she had an extra one GIGI Honee Wax Warmer and get the Super Lube at Harbor Freight best price when you add the 15-20% discounts when they have them.

I use melt about half the capacity of the warmer not sure how much wax that is in weight and 1/4 of that super lube tube.
Its not really that large of a warmer enough to get a chain in with plenty of room above it. I also have one of her really large warmers but its way to big for my chains LOL you could early put both hands in it, I could do all 14 bike chains at once in that thing.

Chain stays very clean and quite for a long time and does not collect dirt. I'l wipe the outside of the chain down and thats about it after riding sometimes.
