What is this on the white fascia and how to remove?

What’s causing this black staining on the white fascia? I’ve tried my standard SH softwash and scrubbing with LA’s Totally Awesome, but it won’t come off. The staining is smooth to the touch with no raised or rough areas. What chemical would you recommend to remove it?

It looks like the paint is compromised and that’s what you’re seeing. The brackets holding in the soffit panel look oxidized as well.

Did you try a stronger SH mix than just house wash?

Hopefully this is a pre-wash picture as the spots/stains on the white vinyl soffit looks to be what I would consider “normal” mildew.

I’d be hitting that with 3% pump up sprayer

I brush most of the gutters and fascia for the homes I do because they use oil/coal/wood all winter and 1 thermal inversion and it lays on there good. 90% of the time I see that I tell the homeowner that isn’t coming out, might lighten it. Aluminum often goes black on older homes, either it is pitted from the wind and acid rain or the paint is just almost gone. They are almost always heavily oxidized.

That is all for my area. I don’t know about your area. There are maybe a handful of houses around here without a chimney (a lot of those are power vented, just not a classic chimney). Our temps are 26-41 today with snow and tomorrow is 24-35 with snow forecasted. I’m done washing. Rig is half tore apart. Those temps are Fahrenheit for our friends north of the border and our overseas friends - so about 3-5C today and a tad colder tomorrow.

Normal house wash takes care of the guy’s problem 99% of the time for me. But like you said, regions are different. Never had any issues with chimney soot around here.

When people come on here and ask why no one responds to the newbies sometimes, point them to this thread.

Three guys that have been washing for awhile chime in right away trying to help a guy.

And he ghosts everyone.

Hey, there we go! That’s what I’m talking about!

So what did you try and what was the fix?

We probably run our furnaces for a longer time than you do. My oil furnace has been running since September (on and off) and is in constant use now. My pellet stove will be fired up here in about a week or two and will run everyday nonstop until about the end of march. I will probably go through about 1.5-2 tons of pellets and 3-4 tanks of fuel.

You can smell the wood and coal in the air driving down the road. We don’t have NG here. Well we do, they drilled like crazy and have wells all over but no infrastructure to get it to the homes.

Man where the heck are you located?

Edit: Oh PA, kinda rural out there for sure
