gutters

[desi 14]

Does water and aluminum create electrolysis which binds mold to the gutter? If so, how can I get moild treaks off gutters? My 3400 psi 4gpm unit does not seem to be pulling much detergent. Any suggestions? Lastly, I use a chemical tip from Pressure tek. It also sprays 30+ feet. I cannot reach the top of a 2nd story house. Without using a ladder , any suggestions.

thanks

To answer you questions...

1. I find hot water and a butyl detergent removes the streaks

2. Replace the chemical injector on the pressure washer

3. I use extension wands for high areas
