I just have a couple of questions for my Savannah Onyx PitBoss that I bought in late March early April. I go to clean it and one the heat deflector plate is horrible to clean I read to only use a plastic scraper and it gets none of the buildup off at all. I'm also having trouble with a little rust inside the cook chamber and the heat deflector plate although I've seasoned it a couple of times so don't know what I'm doing that is causing rust only having it for 6 months. Any kind of help would be appreciated because it cost a pretty penny for me and wanna keep it for a long time
