I have
manna pro egg cleanser. Its, essentially, a detergent. it is NOT a sanitizer.
I use it for duck eggs I collect for my own household use to assist cleaning them, since ucks drop eggs, well... everywhere. My clay soils routinely stain them - and the
Manna Pro in no way improves that. But it does help remove any solids stuck to them.
The
MannaPro isn't suitable for eggs fo sale here in FL under my limited poultry and egg license. They get an air dry bleach spritz or dip at as tested concentration (I have rolls of test strips specifically for it). While chlorine isn't the only allowed sanitizer by the State, its one of the most readily available.
For those wondering? "Water, Yeast, Citric Acid, Potassium Sorbate". Potassium sorbate is a preservative, effective against a range of microorganisms. The yeast and acid *seem* to be effective at dissolving enough of the outer bloom to help slough off things stuck to it. But a worn buff puff and mildly hot water 105-110 degrees is just as effective, and what I use to clean my (chicken) eggs of "stuff" before the sanitizing dip. The citric acid is also good at removing tiny calcium specks on the shell when they are present.
Buff puff then gets rinsed and goes into the spent sanitizer till next needed, so as not to be a source of cross contamination - since even after dipping, the chlorine levels at the rate I mix it remain in target levels. The sanitizer has to be replaced every time - temperature is an important component of the process.
