ok I just watched doomsday preppers and had a couple of questions.

one lady was rubbing down eggs, I am assuming from the grocery store since she didn't have any chickens, with a mineral oil? Then she said they would store in cool place, NOT frig, for up to 18 months. Does anyone do this?

Second, the same lady was taking blocks of cheese and dipping them in wax and said they will age but remain basically the same on the shelf. Any one doing this?

I would love to catch the sales on both and love to maintain them way past the dates . If you can let me know your techniques or just tell me where to look here on the web. Thanks!
