I had a fire smoldering while at work that I was unaware of until it was too late. Luckily, it only melted a green plastic chair down into the colored concrete. Is there a way to remove this plastic without ruining the concrete? I tried power-washing with no results. I tried acid with unequal results. Any help would be greatly appreciated.

If you didn't use a 3,000 PSI power washer with a red tip, you wasted your time. I would try that first. Those yellow home 1,500 PSI power washers are worthless for heavy work.

Since melted plastic gets hard again once it's cooled, can't you just get a razor scraper and peel it up? There's no way acid would have worked, as plastic is unaffected by acid. That's why they sell it in a plastic bottle.
The big pressure washer Pulpo mentioned would probably work, but a red tip will most likely blast track marks into the concrete surface.

You don't have to worry about the pressure washer making marks in the concrete. Test it in a corner somewhere if you really want to be sure.

I know how to remove it, but I want to hear the story first.

Looks like we're not gonna hear the story, but how about your solution Tscarborough? I hope it's not "throw a rug over it"!

Dry Ice and a Dremel works.
