How do I remove concrete?

[98-Supra-JE]

I drive a 2007 Dodge Ram 2500 Cummins Megacab. I detailed the entire vehicle last week only to discover that I had driven through concrete or masonry cement of some fashion. I've got concrete splatter on my right wheel well, the running boards, the fender, and the paint just behind the tire above the running board connection.

I've tried to use a pressure washer..... I've even used a friend's pressure washer with high pressure.... but I don't know how to get it off w/o damaging my paint or the chrome Westin steps.

Any advise would be appreciated.

Found this, hope it works

The best explanation/instructions I've found is from the following website:

how to remove concrete from paint

Quote: "Actually all is not lost. After being a Cement contractor for
20 years, I have run into this on a regualr basis and there are a few
things you can do. First, you didn't say how heavy the splash was, so
I will give you both methods. First if it is light, grab some Vinegar
from the wifes kitchen. Put some in a spray bottle and apply to the
spots or splash. If it is a light "shadow" like splash, this shoud
take it off. However, if you got the real heavy duty chunk stuff stuck
on the paint, you will need the heavy stuff. Find someone with a pool
and borrow some muratic acid (that's right, acid) and put it in your
spray bottle. Get your hose and put your truck in the street or in the
dirt, not your concrete driveway!!! Spray the affected area and after
the concrete starts to bubble for a few moments, wash it off with a
hose. The acid will counter the alkali in the cement and make it wash
off easily. The precautions you need to take are not to get it on
unpainted metal (like chrome or alloy wheels) or on rubber (would
stain it, not eat it). The acid will not harm the paint, and a coat of
wax after your done is all that is needed. Cement truck
owner/operators have used this for years to keep their expensive
investments on the road."

Thank you for your prompt response! I will try the white vinegar tomorrow morning.... I don't think my splatter is bad enough to merit the use of muratic acid.

My wife just confirmed that we've got some in the pantry so I'm eager to give it a shot.
