These are over 30 years old rectangular profile titanium zinc gutters. Wonder if they've ever been cleaned before. Hung the shop vac from the ladder, scraped all the dry crap off and vacuumed it clean. Did the south side today, cleaning, looking for bad or cracked solder joints and repairing them as I went. The last part wasn't soldered at all on the bottom and very badly on the two vertical sides. Cleaned all the bad joints with sandpaper and used some special glue from a caulking gun to fix.
