I've got an old customer who has a combination of rust and what appears to be calcium deposits on one area of his roof. It is where the AC drain pan pipe drips. I'm sure the rust will come out with F9, but I'm not sure if F9 will take care of the accompanying calcium.
Anyone out there know if "CLR" will be safe to use on composite shingles????
Thanks.. Mark

F9 has an efflorennces remover that should work as well. It should be able to remove both stains.

Thanks, Michael. I'll give it a whirl. I was really hoping F9 would be the answer for both.

Well, the F9 took the rust (of course) and the calcium off the window glass, but neither the F9 nor the CLR was able to even touch the white calcium buildup on the composite shingles.
Anyone have any ideas for next time?
(pix not in order, sorry)

Mark did you use the regular f9 or the f9 efflorennces remover?
Mark Fermoyle said

I used the regular F9, Mike.

Gotta use the other one they got.

Mark, we make another product called F9 Efflo (Efflorescence and Calcium Remover). If any product has a chance at it, this would be it. I would go straight and light.. but it will need to be agitated some how. We use brooms, brushes and floor tools (for flatwork) but you will have to be careful on the shingles. If you have calcite, then the job could be futile.

Mike & Craig,
Thanks, I'll be adding F9-Efflo to my arsenal.
Craig, what is "calcite"? How do I recognize/ID it?

look on internet. It looks glassy like a stalagmite in a cave, usually kind of wet looking and whitish color

Hi Craig,
It's good to see you in here!
I just Wiki'd and Googled calcite, but can't get any decent pictures of what it looks like. At least on a roof.
Is calcite efflorescence a byproduct of the air conditioning runoff?
I hope the drain pipe is going to be fixed ( or finished) or the problem is just going to come back, anyway.
Still learning,
vic

Hey, Vic,
I explained to my customer that he needed to re-plumb his drain pipe before replacing his roof. The ball is in his court now. We'll see if he acts on my advice.

Well said, Mark. You have a great logo, btw.
There is a lot of good information in it :)!
