What would be the best solvent/acid/whatever for removing a large amount of Acrylic Latex house paint from a cement garage floor? What would be all around most effective? What would work but be gentle on the surface of the concrete?

...Sorry, I didn't know what forum to put this in...  

I would think some simple paint thinner/remover from the hardware store and a cotton mop would be the way to go.  use a garden hose to help rinse. seems like the obvious solution.

If it's <48h or so Denatured Alcohol (Ethanol) will work, beyond that I belive you'd be limited to mechanical means (pressure washer) or possibly muriatic acid.

It's actually several months old. What about a NP solvent like Toulene? Or is Muriatic Acid the way to go?

If it's several months old, I would go with the muriatic acid. What type of concrete is it? Smooth (like inside a garage?) or rough (like a driveway?). If it's smooth, the acid will etch the concrete to look like a driveway. If it's already etched, it won't really make a difference. They do sell paint remover at hardware stores. Something hardcore like aircraft stripper (DCM if I remember correctly) would probably work. peace

It's the inside of a garage, so it's smooth. I don't want to etch it to be rough, so the HCl is out. So is DCM the best option? Will it scratch the concrete too? What about Toulene? Appreciate the help so far, btw...

Many solvents could work. I suggest toluene, DCM, acetone, or xylene. Plain ole paint thinner might work too. If you have these solvents, just pour some over the paint and try to clean it up. If one doesn't work, try another. If you are wondering which solvent you should go buy to clean it up, I suggest one of the above. What kind of paint is it? Latex? Polyurethane?

It's 100% Acrylic Latex house paint.

Find a patch and apply all of your solvents to a different area and then see which ones work.. report results when you are done...
