I have a Gruyere that started life as a washed rind , then I decided to wax it , after a month or so of rind development , I dipped it in very hot wax , hoping to sterilize the surface somewhat , so far , it looks good , nothing growing under the wax , it's been about a month now in wax.
I should mention that I use a small deep fryer as wax pot , I got the wax to 300 degrees beforehand , I know it's kind of dangerous getting it too hot , but I keep a fire extinguisher right at hand.
I will double check it closely again today and let you know if there are any problems with it.
