I had one of my employees move all of the crap that was in our way, on a nearly completed remodel, onto the new front porch. The porch is a concrete slab, (slick finished). He sat a bottle of purple pvc primer down that was leaking from the bottom. When we discovered it most of it was wet and I removed it by sprinkling portland cement over it then sweeping. But, about a dinner plate size, had dried and stained. Any ideas how to get this up.

I did that once on my garage slab, and 3 years later I couldn't even tell where the stain was. Not that your homeowner will be too thrilled, but the stain will likely go away.
"dilution is the solution to pollution" - maybe you could work it over with toluene or acetone - similar solvents to your purple stuff.
I'd be tempted to try some acid. Once all of the employees bones are disloved try ectching the surface with muratic acid. It may not remove the stain but perhaps give you a sound base to apply some portland and cover it and get your smooth finish back.
Pressure washer???
pour the appropriate solvent or thinner on the spot and cover it with a newspaper. It will absorb the spill.This works when you have oil spots on the driveway..++++++++++++++++

Mrfixit - I have leaked transmission fluid and probably a little engine oil on my inlaws new asphalt driveway - what solvent do you recommend w/the newspapers...

Do a search. This was just discussed a few weeks ago, although the purple stain was on a fiberglass bath tub. I think someone said use the clear PVC primer as a solvent to remove the purple primer - makes sense - I guess...
I would look for one labeled cleaner for pvc. Most of the primers I have seen are a diluted solvent glue and would leave residue.
Brian, I would try paint thinner. You pour a little on the spot, then add the newspaper on top, and then add a little more thinner to soak the paper.Let it set and when it dries it absorbs the tranny fluid.Good luck.++++++++++++++++

Don't use acid unless you do the entire porch -- it will etch the surface and leave it looking different.
happy?
Thanks guys it looks like I have plenty of things to try before I break out the jack hammer.
Call the manufacturer and ask them.
I'm the one with the purple stain on the shower stall. I called Lasco and they told me to try WD 40 or acetone. The WD 40 did not work and I haven't gotten around to trying the acetone yet. You might want to try it though. good luck.
Yeah, I would think that acetone or laquer thinner would be the way to go. Or one of the "liquid sandpaper" products (essentially the same stuff). Just make sure not to use anything containing oil. Put it on and then cover with baking soda or diatomaceous earth (or maybe cement powder), then a little more of the liquid. Stir to a paste and work in well, then leave set until almost (but not completely) dry. Scrape off and repeat as needed.
If ignorance is bliss why aren't more people
happy?
I would burn it off with a torch.
