Muriatic acid is bad news. If inhaled it can cause pneumonia. The fumes also can damge your eyes. I left a about a quart outside uncovered and it caused a section of my patio table to rust.
That being said it is a good, strong cleaner. Mason's use it to clean up small concrete spills. If you are going to dilute it make sure you add the acid to the water. Otherwise you may get have a small chemical explosion.
