I'm sure I'm overlooking a previous post or a sticky or something, but can I get a laundry list of supplies I can take to my local stove shop so I'm ready for my first cleaning? And how long into this burning season should I go before that first cleaning? Burning seasoned red oak in a 30NC. I have 6" rigid stainless for about the top 20', then some flex stainless tied to the tee with a clean out, and then double-wall stove pipe. Thanks.
