Hello. So I have a MES 40 with the glass viewing window. What was I thinking!!!??? LOL. First smoke spent about 15 mins or so cleaning inside of glass just to see in. Let it go two cycles after that and you can't see through the damn thing. HAHA. Its like cleaning sap off my kids. Is it worth cleaning? Anyone have a quick easy solution? If not I am thinking to just let it go. Thanks
