Did some initial “gunk scraping” (that’s the technical term) today and it was very satisfying.
AAAaaaaahhhh. So good. Still more cleaning to do, but man that was satisfying. For those curious, I used a flat head screwdriver and a plastic paint scraper to scrape the gunk away. Still looking for recommendations on cleaning solutions to use to get the last layer off. Once I clean off the rest of the cobwebs (literally) then the real work can be done.
