Gutter zap

[jgoral76]

Does gutter zap work on aluminum siding like under the gutter? if not why and if so what mix and reaction can i expect?

I have had fair results with the aluminum as you describe with the gutter zap.

I know some guys use gutter zap from exterior. I was at their store in Garner NC and they have a special right now. But two 5 gallons and get another 5 gallon free.I like GZ BUT I have got to give Pressure teks gernade a shot.

I used pressure tek's f13 today and posted about it in "look whats new". If you get some your search will be over.

Hi everyone

I'm new to this site but have been in the business for 13 or so years.
I have always used Spray Nine for gutters. It does a very good job especially on older gutters. I find it cheapest at Home Depot ... about 10 dollars a gallon. Be sure to wash it off BEFORE it dries.

The F-13 from Bob I dilute 20:1 and it takes off the streaks everytime and it's only about 10 and some change per gallon. The Gutter Zap cost the same or a little more and it don't work good even at 2:1. The F-13 in a 5 gallon bucket makes a little over 100 gallons of ready to use gutter cleaner, no other one on the market can beat it, compare that with Gutter Zap it makes what 15 gallons of ready to use, and really don't do that a good of a job.

I have used gutter zap but it seems a little high in price, will try other after this runs out. It did work well
