I have a customer who runs boat tours in a resort area. I have completed several projects for him, and he has another. His boat docks are located at the foot of a very old dam, no longer operational. Essentially at the bottom of a cliff. Above the docks is a footbridge with black steel infrastructure, covered in years of pigeon droppings. I have not visited the site yet, but from memory, its at least 40' up. I know these droppings can get like concrete, or at least clay. Would TerraWash take this off at low pressure?
Looking for a way to do this without a lift, as there is no way to place one, or a crane, as it would cost $$ and have to shut down a lane on a state highway.

I have read lots of blogs, but I don't recall seeing anything on this subject. If you don't get a specific response on this specific surface, possibly you could find some droppings at street level under a bridge or road sign. Then run some tests.
I would try a test spot with Terra Wash. I did a 25,000/SF plastic Eco-Shake job last Fall, that was infested in bird pooh. We use a product called Dirty Bird from Winsol Labs. It does work, just takes a little patience and extreme attention to the direction. It will loosen up, if not completely remove the large globs of pooh. We also hit the whole roof with a 2% mix with Terra Wash, after the initial application and rinse, from the Dirty Bird.
Clean, brand new backpack pump sprayers. it has millions of microorganisms in it, and cannot come in contact with any bleach or other chems, or it will kill them. Read all the instructions and call them for some extra support if needed. it has specific temp ranges and moisture requirements also.
