It’s a lot of poop guys
Pressure!
That’s exactly the kind of job a pressure washer is for
Is this you op?

Don’t dox me wtf
Too late

I can only get so erect
Home depot rents pressure washers for like $35/4hrs. They include soap injectors to add concrete cleaners with the spray, but you can also just dump cleaner on the ground, brush it with a broom then pressure wash.
There’s also a ‘floor maintainer’ which is often used to clean/polish concrete. Either with a bristle brush attachment or various grits of polishing pad.
As others have said, 100% use PPE. Face mask, gloves, eye pro. Concrete dust contains silica which leaves you with silicosis and bird poo (well any animal poo really) contains some rather nasty diseases humans can contract. Keep yourself safe.
How does pressure washing generate dangerous silica dust…?
I gave two options, a pressure washer, and a floor maintainer.
The floor maintainer can be used wet or dry and will grind off a small amount of the concrete during polishing.
Just something to be mindful of. Airborne pathogens from the poo is a bigger issue.
At least one more here in the comments said that, hence my quick comment. All good then and yes, generally don’t breathe shit.
Bird-urine is white, their poo is brown/dark.
Washing-soda or baking-soda ( & if kids are going to be playing on it, or someone’s going to be picnicking on it ) in a weak HE-laundry-detergent solution.
( urine is acidic: the alkali in the washing-soda or baking-soda neutralizes it )
scrub/soak
then rinse.
hth.
Vigorous licking. I mean, really get in there. Commit. Clean surfaces are no joke. You have to be ready to do the work.
You might have a point
