I cleaned my first roof of the year today. The SH that I had was from the last 55 gallons that I purchased Nov. 15th. I was concerned as to how effective it would be after sitting for 3 months. I had 17 gallons of SH and decided to add 15 gallons of H20 along with ammonyx Lo and gave it a try. It was 48 degrees out with a wind chill of about 43. The mix worked great. I had to spray a light 2nd coat on some of the most infected areas but I was surprised at how effective it was. With the cold weather we have had in NC this year I am sure this helped to preserve the SH. I attempted to clean the exterior of the gutters with F13 but just couldn't get them clean. I used a 1 to 5 ration and this still wasn't enough. Has anyone run into this problem. I assume it needs to be a little warmer to effectively clean the exterior of the gutters.

Glad to see you got some work in this cold spell. I still have 30 gal. in my tank. I will be using for house wash next week if it stays in the 50's or better. As far as the gutters and the F-13, it should be warmer in order for it to work its magic.

I remember your hints on this topic VERY well from a late night conversation
My experience scrubbing gutters going into winter, well temps were real important, scrubbed one houses gutters 3 times, It just wouldnt get any better.
It's amazing how much more effective guuter and concrete cleaners are above 100 degrees.
