I thought the same before I did mine but I decided to go with the peanut oil because it was recomended and it ended up working great! Im sure you could use any other oil but I know peanut BUTTER is a great tool for breaking things up (gum in hair, etc.) so I figure maybe the oil has the same ingredient that does that as well? I'd be interested to know if the other oils work as well when it comes to taking off the wax and oxydation...if you decide to try it post and let us all know. couple before and afters:
