I've read the restoration procedure but I'm uncertain on a couple things. Do you maintain a wet edge when using the razor blade or do you do that part dry? Also, what keeps the corners of the razor blade from digging in? On my newer kettles (8 years old), I've used an 1.5" wide flexible metal scraper and it seemed to work well but It's roughly the same width as a razor scraper and it didn't sit flat to the bowl since the bowl is curved. I want to clean up the mbh but don't want to risk damage.
Thanks, Sean
