I have three Goudas that just kept growing mold under the wax , I finally got some of the yellow coating and removed all the wax , cleaned off the mold and re-coated the cheeses , so far no mold is coming back , so hopefully , the natamycin is doing its job.
Natamycin, is a naturally occurring antifungal agent produced during fermentation by the bacterium Streptomyces natalensis, commonly found in soil.
I like the way it goes on , I like the looks , and it seems to adhere very well to the cheese , I would suggest to anyone that they at least try it once.
It is probably all I will use anymore , it comes in Yellow , Black , or clear.
I think pricewise , it is comparable to cheese wax.
Cheers , Jim.
