Hey All,

I have those nasty black streaks on my gutters and now the HOA is busting my chops about them.

I've tried pressure washing, concrete cleaner, scrubbing... even aluminum wheel cleaner. Nothing seems to make a dent.

Has anyone found anything that works well? I'm either going to have to do this from a ladder, or from the roof on my belly and leaning over the edge... so ease of use would be a big plus.

Thanks,
B
 
I'd think some M105 would take that right off. Ideally you'd use an AIO so as to retard the re-staining. I have used my old waxes that I don't want to use on the car anymore on my aluminum cladding on windows and doors, and things like old Gold Class liquid seem to remove the black streaks, although probably not as easily as something with a bit more bite. I would think DG 501 would work well.
 
Last summer someone posted about a gutter cleaner that you can buy at Ace Hardware that you simply spray on and leave it. Over time it does the cleaning by itself. I tried to search for it and had no luck, hopefully they will chime in.
 
Go to home depot and try some tsp, tri sodium phosphate powder mix it with water and give it a go.
 
I used to be in the roofing, siding, decks, doors and windows business. Trust me when I tell you that Simple Green is all you need.

Zep purple work great too. I did my gutter a few weeks ago. Spray on, wait for 30 sec and hit it w/ power washer. Some stubborn spot needs some elbow grease though. Be care climbing up the roof, you don't wanna end up in Neuro ICU
 
Wonder how Simple Green would work in a foam cannon for cleaning gutters.
 
I have never had to use it, but I have been told by several friends that Simple Green will do the trick for you. 303 also has a cleaner that they say will work.
 
Meguiars APC+ is some amazing stuff... I would try it.

We always would spray the Simple Green, wait about 10 seconds and wipe with a terry cloth. Worked like a charm

You can use simple green or purple power. Brush on and agitate. Use your hose to rinse. You do not need a pressure washer to rinse. A brush attached to an extension pole to apply and agitate works wonders. Black streaks are are called tiger striping in PW world. They develop as a result of the residue from your asphalt shingles. Granules will run across gutters during heavy rainfall. Any butyl based (i.e. active ingredient in degreasers) will work.
