I would like to Kasher my Fleishig oven to Milchigs, make some Milchig food and then Kasher it back to Fleishigs. I was wondering how I would go about that? My oven has a clean button.
An oven may be Kashered by turning on the self clean for a full cycle. When Kashering from Milchig to Fleishig one may Kasher even by leaving the oven on for a full hour on the highest setting.
The custom among Ashkenazim to is to avoid Kashering from Milchig to Fleishig and back on a regular basis.
See in the link below for the reason, as well as when this custom does not apply.
