Spray paint removal?

hej, so this was my first time working with spray paint. I did it outside on a tarp, but it was super windy. I didn't realize the wind would have like....a mist?

Anyway, this happened to our back patio now, and it is obvious now that ive gotten the project done, put everything away, and looked back. v.v

are there any tips for removing the paint from this concrete? imma try to include a picture to show my shame.
