Smell my cheese
I have never touched my oven in any way in regards to cleaning it. I bought a new unit a couple of months ago and was very keen to experiment with the new unit compared to the old regarding the cleanliness of the oven in relation to performance. I found no noticeable difference whatsoever between the two units
I always thought it made a difference IME. Although I clean the bottom screen at the same time, so that might be the difference
