Gutter Zap is a product sole right here on WCR. The description reads as follows:
Product Description
Xterior Gutter Zap. Designed to clean the black streaks off gutters caused by electrostatic bonding. Spray on effected areas wait a few minutes and spray off, no high pressure needed. safe with vegetation and painted surfaces.
The video however shows the product being brushed on and agitated with a brush before being rinsed off with a garden hose. So does it work as directed or not?
It will work as directed but it can also leave over spray marks on surrounding areas. I would recommend spraying down all surrounding areas before applying Gutter Zap in any fashion. We have found that brush application works best.
It really depends how built up it is. Sometimes it just melts the black marks right off, sometimes it requires some elbow grease. In the video is one of our workers (ron) he basically does gutter whitening all day. The method he shows here is just the absolute quickest way to do it.
This brush works really good:
mr long arm flow through brush soft
This product just came out specifically for this application:

Chris,
I have a Marxoff and was wondering which detergent to use. Are you saying that the Gutterzap/Marxoff combination would be the way to go?
Sam
Yea its 50 50 the marxoff or the mr longarm brush I posted. You know gutters are different shapes sometimes. On some the marxoff fits the groove perfectly on others the brush conforms to the gutter a bit better.
Thanks for the information guys. I actually have one of the flow through brushs already.
I would not recommend Gutter Zap, i used it on New gutters and it took the paint off. I have talked to several since that have had similar problems
In our window cleaning / pressure washing biz we go through over 15 - 20 gallons of gutter zap a week. It is very rare that happens… If you test a small area before you begin you are safe. How long you let it dwell up there plays into it as well.
Have you found any safe / effective alternatives Kyle?
Not to answer-jack Kyle, but Krud Kutter applied with a strip washer takes the smek right off, haven’t had an issue yet with it.
I had my first 4 gutter whitening jobs last week and it worked great with a fine deck brush and unger extension pole.
So happy with the profitably I put some pics on the website - looking to sell more!
I have been using Gutter Zap for the past couple of years. Recently, from a pressure washers suggestion on this forum, I tried F-13 Gutter Grenade, from Pressure Tek. I looooove it! I don’t know if it’s me, but it seems to melt the black streaks away much faster than Gutter Zap did, and less agitation with a brush needed. On Pressure Tek’s website they say that Gutter Grenade attacks the oxidation, not the paint.
A pressure washer is 10 times faster.
+100
F-13 is Potassium Hydroxide based and does a better job of keeping the paint safe while only emulsifying the oxidation while removing the electrstaticly bonded stains.
A pressure washer won’t get the black streaks off and leave the paint.
Do you price gutter whitening by the linear foot? If so, how much do you charge?
A dollar per foot per story.
Be really careful when you handle or are exposed to anything with Potassium Hydroxide in it. With its high PH, it will burn your skin
