Input Please...

As some of you know I am building a camp, this past January I picked up a ton of used rusty barn tin with no holes in it "I'm trying to make it look old" I brought it home and stacked it on a few pallets on my garden about 10' from my ash pile.
2 weeks ago I was ready for the roofing and as I was loading it I noticed there was a white grey mud or paste between the sheets, which I am pretty sure is the fly ash that was carried by the breeze and got trapped in the sheets.. I have installed the roofing and it has rained a lot in the past 2 weeks. Do you guys think that the rain will be enough to wash the sulphur off or should I scrub it with something to neutralize it? I did go up in the rain last Monday and run a car wash brush over it but it didn't seem to help much

Thanks dana

Power wash it? You could add some potash to it ... but washing off well is a concern as well as the potash being on the ground afterwards ... maybe just a washer with soap.

What about the under side?

Depending on roof pitch, rain will do fine--it's already screwed/nailed down right??? Find something else to worry about!!

If your still worried, get a box of Arm & Hammer baking soda. Pour it into a 5 gallon pail of water and stir. Spray that over the roof. Non-toxic to humans, pets, and plants. Used to neutralize even battery acid.

The ash pile has been out in the weather I would think. I wouldn't be to worried about having to neutralize it at this point. Let the rain take care of it is what I would do.
