Curb Appeal 14 Report post Posted February 12, 2007 Hey all, I tried to clean off some gutters today with my F-13. It didn't work. I even tried it full strength. I think it froze sometime over the last couple of weeks. Bob at Pressuretek said that freezing will kill F-13. I'm in a bind and I need to finish these condos tomorrow. I can run down to Autozone and get some Purple Power but I read somewhere on here that it doesn't work well in the cold either. Anyone have any experience using Purple Power in low-to-mid-40 degree temps? Any other alternatives I should check out? Thanks as always... Share this post Link to post Share on other sites
