Thanks for the replies everyone! Interesting to see everyone's preferences.
Which brings up another question from me. How do you guys clean your dirty vents?
IE this
Personally, I think that vent is gorgeous. I probably wouldn't clean it one bit.
When I buy a used kettle it gets an initial once over with OOOO steel wool & Bar Keepers Friend. After that, all of my kettles get regular wipe downs every few uses with Simple Green or a similar product. I have a bottle of Weber's Exterior Grill Cleaner, but it's worthless, IMO. The vents usually get left alone because I happen to like the smoked, almost case hardened, look.
