when I first put this FO in it was cloudy for just a about an hour then cleared off, mine was cooled down (crock pot off all night) so I am not sure the heat has anything to do with it, in my dish soap I add lemon EO this last time I put it in hot and it is stunning clear light yellow, my peppermint that was EO was clear as a bell until I ****oo'ed and rather then adding a bottle of distilled water I added a bottle of spring water and oh my I think I almost cried LOL
