I wrote to Anova to ask them how to clean the inside window of the oven. They sent me back their standard blurb from the manual. I wrote back and said that I was specifically asking about the inside window, and "I know how to clean the rest of the oven, so you don't have to tell me again."
Their new reply:
"To answer your question, you can use a dishwasher tablet to rub on the stain and then wipe it off with a damp cloth. Alternatively, if it's easier for you, you can apply warm water to the area, rub the tablet, and then wipe it with a damp cloth."
Since I don't use dishwasher tablets, could someone explain what she's probably saying?
