concrete removal

The edge I bought has concrete slashed on the front of it. The paint and the plastic headlights. Anybody know a good way to remove it?
TIA
John

That will probably be the last resort ...I'm not too concerned with the paint but would like to save the headlights.

chip it off and get some plastic polish and just buff them clear again, Or even a highs peed felt will buff it clear, if there is heavy pitting use some 400 then 600 then 100 grit sand paper, I have done this on an old mercury sable where the headlights were yellow. Harbor freight has a compound called plastic polish in a tube. The paint you maybe able to use a pressure washer to blast it off. Then lots of buffing

The car guys at CarTalk.com recommended muriatic acid to remove cement on a vehicle. They did a followup call on a later show called "Stump the Chumps" and the the acid did remove the cement without any harm to the paint.

If it's just specks of concrete, you may want to try a claybar. They're typically about $15-20, and the kits come with the spray lube for it. A claybar won't damage your paint so long as you knead it while you're working. I've found a claybar to remove most unwanted hard additions to the paint (road paint, tar, bugs, etc). I use Mother's Clay bar, though I've heard Meguire's to be a bit more abrasive, though it isn't carried around here for me to check it out.

**Edit: Forgot, ideally you should re-wax the surface after doing any sort of treatment like this or otherwise.

I haven't tried to clean it yet, I have started tearing it down to convert to 4wd. I probably won't try until after I get it running again...Thanks for the replies.

How much concrete?

first sray with a Hotsy, with a good angle not perpendicular to surface, any clumps the size of a dime or larger give the ballpeen treatment, gently, very gently if you dont want to damage the paint, the more concrete,more patience, methodically work every part of concrete, rinseoff chippings. muriatic acid works well to remove the concrete, Be Cautious it will etch aluminum, may fade plastics color, may etch cheap chrome, glass, any rust or bare metal. DO NOT let it even drip on your radiator! Dilute the acid with water. 10% acid /90% water. Plan on a couple 2-3 applications or more. start with a weak acid solute(depending how much concrete splatter) and add more acid if necessary(acid20%-30%+) , Always try in an inconspicuos-non visable place, rinse and allow to dry before checking for damage.spray application is best. do not allow solution to dry on the vehicle(keep it moving), apply several times, then remove using a medium stiffness brush, dipping in the solution often (to remove concretechips from brush) brushing only the affected area,spray with Hotsy, repeat. wear safety glasses and vynl gloves
