Last Week I Learned... Self Cleaning Oven

I had never used the self-clean feature on an oven before. First I searched, online, for any instructions connected directly to the model of oven we have (Kenmore, Gas). I opted to read through text-instructions rather than watch videos. Actually, I watch one video and it wasn't helpful. So I reverted to text. Basically I learned you first wipe our any excess debris, DON'T use any additional cleaners, plan 3-4 hours of not having oven access, create ventilation in case there is smoke, and the kitchen will get very hot.
