Concrete!!!

[ratbastard]

I run into this problem all the time with work trucks that we detail..... is there any easy and fast way to remove concrete? We've delt with it a couple times and it was no easy task. I manage a high volume detail shop but if there is any easy way it would help me greatly.

I have never tried to remove it from a car but I work in the concrete industry in a testing lab and have some experience. Concrete or actually cement paste is what is on the trucks and it is very alkali. To remove it typically we use acidic materials. Muratic acid is common but I have no idea what that does to the paint or clear coat. Somewhat more mild would be vinegar or other acid materials made for this like LIME AWAY for bath rooms.



That is the only suggestions I have

Top of the Line sells a non-acid concrete remover, it just turns concrete into mud and then you hose it away. I'd highly reccomend it.

It will strip it instantly down to bare metal & then disolve it.. I use it to take the plating off metal...

My painted front bumper got a large splotch of concrete this week, and a search turned up your suggestion. Just ordered a bottle of the RoMix Back-Set Molecular Cement Dissolver from Top of the Line.



I'll report back after I give it a try.



Thanks,

Finally got a chance to try the RoMix Back-Set concrete cement dissolver recommended by "themightytimmah" earlier in this thread.



It is amazing!!!



I'm very thankful for the recommendation and highly endorse this product.

Check out these photos...



This shows the splatter of dried concrete on the front of my car. This was not powdered, but thick, rock hard chunks of cement.

Here's a close-up of some of the small dots of concrete on the top of the hood just above the right headlamp.

After spraying on the remover, I used a soft brush to spread and keep the concrete saturated.

After 15 minutes the concrete was so soft it literally slid off with a wisp of the brush. Leaving behind the shiny paint.
