I just made my first palm wax container candles - love them. But, how the heck do you clean up? I normally use soy wax and feel like I can't use my metal pouring pitchers for that anymore, they are all coated with palm wax and I can't get it off. I wiped them out with paper towels as soon as I poured and went to wash them with soap and water but water at the hottest temp hardens the wax. So, I put them upside down on a towel in the warm oven and wiped when down with paper towel again, but there is still a white film all over the inside of the pitchers. Any advice?
