Concrete splatters on hood

Hey there, i have multiple small hardened splatters of concrete on the hood of my VW from a jobsite (whom are unhelpful and wont return my calls) So its now up to me to try and get this off with hopefully as little damage as possible. Does anyone have any suggestions for techniques or solutions i can use other than going to the car wash which hasn't resolved anything.
Thanks so much,

I know this may sound crazy...but I've heard and read it several different places.

Muriatic acid....yep, same stuff as for a pool. You don't want it to run on any chrome or shiny metal trim. Depends on where it is of course.

The acid doesn't react to the paint, and it took the cement/plaster splatters right off, if the things I've heard/seen are correct.

Prob the same stuff they use in the MIRACLE wax commercials.

You don't want it to hit any exposed metal, like a scratch or a chip.

Hey thanks!

I will do a little research on the stuff, although have to admit seeing the word acid immediately worries me but i will do a small test first and let you know how it goes. I am new to the site so I will post a photo or two of the before and after.

You might try some vinegar, lemon juice, or bathroom cleaner with an acid in it before you try muriatic acid. Though they are milder, there are obviously some safety considerations. You may have to step up to the muriatic but try something a bit more user friendly. Also, what are you going to do with a gallon of that stuff when your done with it since you'll use very little to dissolve the concrete?

vinegar, it will take several applications to do it though, muriatic acid will take at least 2 applications to clean it off, as long as you keep it only on the paint and wash it off after it stops foaming it will work.
