Well, my Cameo order arrived yesterday and I tried it out today with positive results. I didn’t have time to get into a full cleaning mode today, so no photos but just using a pad of wet paper towels and some Cameo cleaned the test area quite nicely. It isn’t the magic bullet we’d all like to find—spray on and wipe off— but it does remove the smoke and grease residue nicely with just a little elbow grease.I’d say that is an amazing improvement over what you showed us at the start of this thread. Thanks for the follow-up post. I need to get some of that stuff.
Thanks, @Winkler for the suggestion. Cameo has found a place in my cleaning supplies kit.
