Go easy on me - I stopped using my WSM about 10 years ago and using a different type of smoker. The WSM sat protected in a corner of my shed so I think all it needs is a little elbow grease and it will look as good as new on the outside. I'd like to get it ready for a nice weekend rib cook and maybe tackle a couple functional mods 
Inside it is well seasoned from numerous cooks but now has dusty white looking mold over most of it? Is soap and water and a nice hot burnoff all it needs? Or do you suggest something stronger in terms of a cleaner?
It is bone stock the way they came back in 2006 and since then I've seen a few improvements in people's BBQ videos that I don't know if are modifications or new parts that Weber or others sell...
First I'd like a lid thermometer - is a 3" River Country the way to go? A link to a nice clean install procedure would be appreciated, or suggestions on an alternativeNext you think is better.
Next I'm giving thought to whether I need a hole drilled (and silicone grommet installed) to pass my ET-73 probes through if most of my cooking is done on the top grill? I'm usually only smoking meat for 1 and don't always use both food grates, so believe I should be using the top grate. In that case is a hole in the lid more awkward than helpful?
The side door - mine has the small round knob that has been fiddly to close the door again. I saw videos where it has a nicer handle - is that an after market thing? A mod? A new part I can order from Weber?
Any other no-brainer mods that a lot of folks end up doing, or an improvement made to newer models that many people retrofit to their older WSMs?
Thanks for helping me get back on my feet
