How do you remove old bird poop from stucco?
Warm water, and then a water jet from a hose.
Thanks for your suggestion, however, I've done exactly this and it didn't touch it. I'm reasonably sure the "poop" is from Geese and has calcified. I even tried vinegar thinking it might help to solubilize the goose poop. It didn't. I don't want to use anything more acidic or basic for fear of disolving the stucco. So, I'm stuck for the moment.
I suggest you use a shovel or scraper. I find that very effective.
The most common method of cleaning is stucco is to lightly pressure wash it. You can also apply some chemical cleaning agent for better result.
