Bat guano off brick

Bat guano/droppings on brick,
Best way to wash it off?

And what about pigeon droppings on brick or on aluminum?

The bat job is far away and i’d like an idea of what it’ll take before i get there.

Also, it’s been sitting there at least a year. Will i need hot water?

Thank you.

So here is the answer to the question for the benefit of future readers in this situation: the bat sh!t came right off with regular housewash although it had been sitting there for 3 years. No pressure required.

This question drive me bat $#it crazy :confused: been looking all around gainesville to test cleaning methods…thanks for the update…hahahaha
