I use the Kent Algae magnet (Scrubbie pad between two magnets one inside one out) for easy scrapin, and the Kent Scraper for the hard stuff. If you do use a razor just rinse it off in fresh water and pad it dry with paper towel. It will make it last longer and not rust (stainless ofcourse). try not to use razors if they are startin to rust, could lead to scratchin. And say clear of the silicone.
