I would try F9 Calcium and Efflorescence remover if the other products he tried didn't work

Jason,

i cant tell from the pics but it appears the streaks are at intervals that match up to standing seam roof above. If so, then it is most likely a stain from the cut edge of the panels. Most commercial standing seam is galvalume win a Kynar 500 finish paint. The cut edges will have exposed metal made up of a aluminum and zinc coated steel. The edges might be forming some oxidized streaks below. Maybe try oxiwash or some form of gutter cleaner.

Just my opinion. Hope this helps.

Jason,

Please update on this if you find anything that works.

My go-to is OneRestore for things like this, so I was surprised that had not worked. Also, if the masonry is in good shape, maybe a hot water pressure washing? My first thought was also that the pattern looked very regular, like it was the result of some specific part of the structure causing the stains. I thought maybe caulk, but OneRestore should have taken care of that, although I usually use it in combination with hot water pressure wahing.

Thanks Chad. I will. He's tried heat as well without any luck.

Is there any chance those bricks were made with concrete?

Maybe the slurry coat or paint has faded?

Just a wild eyed guess, remembering the first 10 minutes of AC's presentation at Rosenstein's in Carson.

If they have made slate tiles out of concrete, it's not too great a stretch to think they might do it with bricks, too.

I agree with John those streaks are coming from the roof. Purple power might just do the job. Full strength

How did this work out?

Looks like brick veneer overlay with possibly metal studs every 24".

May be moisture wiking (oxidation) from the studs if rain water runoff is getting to them.

That's what it looks like to me as well.

He's still experimenting. I've been talking with him by phone to try to help. This is holding up a $20,000 check for him. I've been swamped and haven't been able to get down there. I wonder if we have any "in network" guys that could help him out?

Try muriatic acid. Start with a low concentrate first. Then boost up if needed.

Paul,

Your truck looks AWESOME! However..... Please remember the BB rules are that you need to have a professional head shot for your avatar. Your truck can be in your signature instead.

Thanks,
