My cleaning lady used a sponge to clean the fleishig oven.
She then use the Same sponge to clean out milchig oven.
Both ovens were cold. The fleishig oven was used in the past 24 hours and had splashing from meat that has accumulated over the year.
The Milchig oven hasn’t been used for milchig for the past month.
She most probably used hot water with the sponge when she was cleaning.
Is it okay to continue to use the milchig oven?
Yes, because the water that was used was not even a kli aheini. The water went from the sink to the bucket, and then on to the sponge then to the oven wall. Do the same as I told you in your previous question.
