Should I go for it?

I've used MM cleaner with no ill effects (at least to the aluminum in my previous Q320). Not sure if those castings are different from a Genesis

MM Grill cleaner contains sodium hydroxide....main ingredient I think. It is basically lye and it will eat away aluminum. But only after a long time. It is fine to spray on and let set for a half hour and then scrub it off.

the members mark grill cleaner is the cats meow for the inside of the lid. Just be careful to not let it sit too long on the aluminum. I don’t think it’ll mess up the aluminum quite like easy off does, but it’s better to not risk it.

Some bar keepers friend and a scrub daddy for the outside of the lid and other SS panels. Just remember to scrub with the grain of the metal.

Nice, Thanks!
