F-13 Gutter Grenade Questions

There are quite a few threads about F13 already but most of them are very old at this point so I thought I would bring my questions up in a new discussion…What I’m trying to figure out is what I can safely use it on. The other day I removed tiger stripes from a section of new gutters (< 1 year old) and I was very happy about that. Then, I went around to the side of the house where the gutters were much older and stripped all the paint clean off my test section. I was using 10:1 dilution…I would very much like to advertise gutter whitening as it’s such a great add on service. However, I am honestly nervous about using it. There aren’t any good “How To’s” out there. How can I tell what kind of gutters I can safely use it on? Newer, white gutters only? Gutters that have factory paint only? Is there an obvious difference between factory paint and after market paint? What do you guys do if you accidentally strip the paint off? Am I over thinking this? Help a brother out. Thanks.

I don’t do gutters but you might want to check out pressure washing resource if you haven’t already. Those guys do more of that stuff.

Thanks. I’ll give it a go over there as well.

They are at the end of the original post, my friend. I’m trying to figure out what I can safely use it on. Newer, white gutters only? Gutters that have factory paint only?

I stripped many a gutter with it. It just comes down to dwell time. You left it on too long. You may be tempted to dilute it more but I wouldn’t. I actual do 3:1 and just wipe it off quick. If you do strip it just repaint the area with spray paint. Its actually very easy. Bring cardboard to avoid over spray. I’ve actually just painted whole gutter sections because it was quicker. Customer loved it. Just get the right color.

I just brush it on (20:1), scrub immediately, rinse immediately. Works great!
