New gutters already have tiger striping

Hi - was wondering if there's an explanation for why our new gutters already have tiger striping on them? They were installed in January and within 3 weeks time they were already striping and now there's stripes all over them, making them look old & aged. They're white by the way.

Is it inferior materals? Do they make gutters that won't do this?

The company that installed them made it sound like it was just something that they do and that they could come by to try to clean them up & wipe off, but the stripes didn't budge at all.

Thanks in advance!
Angela

You have mildew and tree pollen on your shingles/roof and anytime it rains, the runoff will stain the gutters. Like anything that is white, it is going to show dirt, so gutters need to be cleaned. No I doubt its anything inferior although I am sure that some painted surfaces are slicker than others and might stay clean longer- or if they are not as slick- get dirty faster as a result.

If you bought a new white car in January, it would probably be a little dirty by now as well.

Your best bet is to get a long scrub handle and a bottle of formula 409 or Westley's Blech-White and give them a cleaning and a hose as needed.

Thanks. We got a new roof along with the new gutters. While it was spring after the gutters were installed, I still find it hard to believe that there would be that much staining. It's everywhere and the gutters look old now. The installers came back & tried rubbing them/cleaning them off with wd-40 but nothing budged. I have a feeling if I were to go out there & try with some other solution that they wouldn't look any cleaner, but I'll try. Thx

Well, one component of shingles is asphalt, and asphalt is black so it could be that too... not sure you will get away from it.

The product I mentioned earlier is actually spelled "Bleche-Wite" and I guess some people online complain that it isn't as good as it used to be (Black Magic is a name change from Westley's, maybe they changed the formula too).

Seems odd to me that it's that noticeable this soon, but am still inclined to think that it's mildew, pollen, etc., as opposed to an inferior product. Can't say though, so you might find out what material they used, and see if you can work your way back to the manufacturer, or a district manager. But, assuming it's nature, we have had excellent with TSP, available at any hardware store or big box. Our 40 year old gutters look almost new when we're done.

I suspect it's run off from the shingles most any good detergent should remove it providing you use enough elbow grease
