Instead of blowing out my wick I use a wick dipper. I saw this several years ago and you just dip the flame in the melted wax and it puts it out, no smoke. Just straighten your wick back up and its ready for next burn. You can just use an old knife or similar to dip your wick with. Another thing I learned from this forum was to twist your wick several times so when your wick burns it will gradually untwist and burn all around. I use a wick bar to hold my wick centered and this keeps it from un-twisting before it sets up. I use cd wicks in my 4786.
