I have had my 22.5 WSM for about a year now and have really enjoyed it. I have used water and a towel to clean the outside but after some of my last few holiday cooks, the water and towel just dont seem to cut it anymore. Can anyone give me some tips on how to keep my WSM looking good? Also, I think that the enamel on the lip of my lid if flaking off. I am hoping it just residue but I doubt it. Any ideas on how to handle that? Thanks in advance.
