First try scotch pad and Barkeepers friend, Ajax, or comet type stuff on the lid. About the grates. Mine were in similar fashion, and I chiseled, and grinded all the rusted and flakey enamel off, seasoned them with oil or tallow, and now treat them like a cast iron skillet. They are working fine. I wish I had a before picture, but this is one I just rehabbed yesterday - It was a rusted up mess. I have done about a dozen Qs, they all suffer the same problem, and I have managed to save them all so far. I think you could also if you want to put some time in.Lots to think about. Thanks guys for all the valuable info. Shifting gears, what do you guys use to clean the lid? I've used soap and water to get most of the grease off but there are still some burn marks. Is the only way to get rid of that repainting? View attachment 25589
After seasoningJust wanted to provide an update on my Weber Q120. So after doing a bunch of research, I ordered new aftermarket two piece cast iron grates (https://www.amazon.ca/gp/product/B07SBSCVXJ/). They were pretty affordable (~$45) compared to the OEM ones so I was a bit skeptical.
They shipped pretty quickly and on first unboxing seem pretty good. No major blemishes, scratches, or pitting. They seem pretty substantial as far as weight, though they were lighter and a bit thinner than the OEM one piece (I don't have the two piece available for comparison).
The included clips are a pretty good fit for my Q120 and the grate sits pretty evenly.
All in all I am so far satisfied with my purchase. I am seasoning them now and will update after my first cook. Thanks again everyone for your help/advice.
