dried cement on late model Jeep

[Red Hawk]

Mike, a coworker was behind a car that hit a white chalk like substance in the road & created a huge dust cloud. He said he had to stop because he couldn't see. Turns out, the white stuff was concrete mix. With it being the rainy season in central Florida, it rained one his Jeep that same day. With his Jeep being covered in concrete mix, the rain made it hard. He said he pressure washed & scrubbed to get what he thought was all of it. Turns out he missed a bit. The white stuff at 4 o'clock in the 1st pic is concrete. The other pics also show remnants. He keeps his Jeep immaculate & this is bothering him. What do you recommend to remove the hardened concrete from paint & plastic bumper trim?Imgur: The magic of the Internet Imgur: The magic of the Internet Imgur: The magic of the Internet

Plastic razor blade and thick sudsy water. It'll slide off effortlessly. Had a vehicle with the exact same situation last year.

This is exactly what I was going to say. After its all gone, clay to get any dust out then polish to repair the clear coat.

An acidic based cleaner would desolve the cement. Just be carefull to not get on the glass. A water spot remover could work. But can be not strong enough to desolve it. You could even try with Duragloss Aquawax which is on the acidic side of the ph level. And could be an option to reach out someone that works with cement and ask them what they use when they get on their semi-trucks.

Did you not see Bob's post above mine? His recommendation for approaching it from a chemical disolver stand point was perfect. If the OP doesn't have access to that product, they can opt for the plastic razor blade method and still inflict minimal damage to the paint.

This was covered in a previous thread and the information Bob shows above was concluded to be a superior method for removal.

Sorry I missed this, been a tick busy lately teaching car detailing classes and typing out how-to articles.


I'd recommend the same thing Bob recommended.

I've asked Autogeek to carry it in the past but my guess is not a big enough seller to move any quantity.
