So I just got the MES30. It used to be so clean 😜. Then after I seasoned it it got a film inside. Then after my first ribs yesterday now it's really not new anymore!! I warped water tray and drip fray in foil so that helped. Question is do I obsess over keepi g it clean or just accept that smokers get dirty and you can't clean it like crazy after every use?? I'm told the dirt inside is BBQ goodness and to leave it alone. Thoughts?
