How do I remove dried cement from door & running board?
Adhesive remover. ADDED: Oh, do you mean concrete? Good luck. Chip it off...?
If it hasn't hardened for very long, Like weeks, try water and a stiff nylon brush. If needed take a plastic scraper and try to pop it off being careful not to gouge the paint Usually if you get the cement wet it will loosen from paint. I have removed cement from aluminum siding this way. Good luck
Try good ole' WD40 it's know to take tar and alot of other road grime off cars.
