how to remove paint spots soaked in concrete

The previous owner left white paint spots all over the concrete porch and as you can tell the concrete is getting very discolored from over the past 7 years. I used my pressure washer yesterday, but that didn't do much. What's my best approach to make this area look better? Paint stripper, 80 coarse sandpaper, etc...

Probably the best way is to 'gently' scrape off the paint and then reclean the porch floor. A chemical paint stripper would also work but would be overkill and might discolor the concrete.

Thanks. What should I use to scrape it off? Should I avoid using a metal brush?

A putty knife should work well. The smaller contact with the concrete the better. I wouldn't use a wire brush.

Thanks. The directions for the paint stripper say to leave it on for only 15-20 minutes. Is it safe to leave it on for 1-2 hours? Will that make it easier to remove the paint?

Paint stripper has to be on long enough for it to work but if you leave it on too long - it will allow the paint to harden and might not come off like it should

NO!

That is not really meant for concrete and will not last on concrete.

That's what I thought. It says it's for concrete though? Should I stain this area then to make the concrete look more appealing? It's an eye sore now.

You could use a solid concrete stain to dress up the porch floor. I've had good results with H&C Concrete stains available at your local SWP store.
