The ingredients of the
Manna Pro Wipe N' Wash eggs wipes for sale at
Tractor Supply Co.:
"Water, non-ionic surfactants derived from corn, palm and coconut oils, water conditioner, preservative - less than 0.2%"
I looked up what a "non-ionic surfactant" is. It's basically alcohol. Water conditioner is some stuff I can't pronounce - salts and glycerin mostly. And "preservative"... I don't know, table salt maybe???
I'm not sure I believe that rinsing my eggs with tap water is any more damaging to the natural coating of an egg than a mixture of alcohol, water conditioner and salt would be. Plus, the instructions on the product say to rinse the egg with water before and after using the wipes, so what's the difference?
I'm sure preserving the natural flora of the egg shell is really important if you're trying to hatch them, but I'm just trying not to eat poop, you know?
Mineral oil is found in the laxative section of the drug store. I know that because I just bought some to oil some beautiful wooden spoons I just got recently. The instructions specifically said to use mineral oil because it wouldn't go rancid like cooking oils would. Before I read that I would have happily used olive oil or something. I guess that's one of the benefits of using a petroleum product. As much as I would prefer to use something plant-based rather than a fossil fuel, there's no denying that is one of the benefits of mineral oil. It does not go rancid. Now it begs the question, will mineral oil-coated eggs give you a mild laxative effect? Who knows, but I believe @pcooley 's 91 year old grandmother when she says it works to preserve eggs.
