Fallout or road grime?

It’s been awhile since I’ve posted but been doing few jobs here and there. Who’s got thoughts on what this is. Multiple applications of roof mix and hand scrubbing is only way to get it all off! I tried pressure and still left residue. But I’ve never seen fallout be brown….thoughts ideas are all welcome.



Sorry I can’t be of any actual assistance, but, hopefully you are charging for a “restore” and not just a cleaning.

Looks like just oxidized vinyl, and you’re removing the oxidation. Those blues can turn all sorts of colors when they oxidize. Purple, brown, grey

It’s oxidized and you’re taking the color off! That’s not going to be fun to even all that out, and when you’re done that house will be a different color.

It’s not blue it’s green and it’s not oxidation. I don’t think anyways or I wouldn’t of took the job on. It does not leave the chalky residue when rubbing on it. Sh loosens it and makes it slimy. But still has some residue left. With some hand scrub the siding looks like new color again.

Call it what you want to, I bet ya $5 you can skip the sh at this point, use degreaser and a soft bristle brush, and it’ll solve your problem. That’s industry standard for removing oxidation… I mean road grime

It’s oxidation. The gradual fade under the eaves is a dead giveaway. Almost normal color near the top where it’s in the shade most of the day and considerably more oxidized down lower where it gets sun all day. You’ve got an oxidation removal job on your hands. Hopefully you charged accordingly since you’re now too far into it to turn back.

Well majority rules. I’ve just never seen oxidation turn brown . It’s always white when it rubs off. Siding is only around 12 years. So strong degreaser and scrub brush it is. How long we think it’ll stay “clean”?

Some people have tried using a wax product after restoring the sheen and had decent success but I don’t think we’ve ever had any long term updates from those jobs. I personally don’t offer oxidation removal but maybe some others will chime in.

DisplacedTexan thank you for the insight always welcomed!

I encountered a commercial building like that last year. A pinkish look on the siding.

I tried every degreaser I had. Nothing worked.

Finally I tried aluminum brightener since I had nothing to lose. It worked.

Yeah I wouldn’t go degreaser, I would go acid. One Restore or Cleansol BC or a gutter brightening product, and scrubbing.

How long do we think it’ll stay looking revamped? Or will it be a gradual decline overtime like original. Thanks

Gradual, but that’s not your problem. You’re there to clean and maybe restore, not preserve unless you specifically guaranteed that.

No they and I understand that. Was just curious how quick it would turn back. I’ve known them for a long time and was hoping it wouldn’t turn back next year. We went into it with low expectations and no promises. So I’m doing ok so far.

There might be some UV protectant you can buy but just speculating.

What product(s) did you decide to try? I’ve had success with degreaser, but I’ve also read a few opinions on here from people with more experience that go against using them.

Tried a strong degreaser first it worked but still quite a bit of scrubbing. I’ve got cleansol bc coming. So we’ll see how it does and I’ll let you know.

Should have ordered you some Britenol also. It’ll work better with less effort. Or just go buy some wire wheel cleaner, spray it on , let sit for a min or 2 and rinse off
