Hellos fellow Geekers,

Most of you know I own a detail shop , I need help on a truck that will be coming in on Thursday.
The owner of the truck traveled down a road that was under construction and now has "Concrete " under fenders and on wheels.

Question is what would be the best method to remove it?
Is there something I can buy that will make it easier to remove.
It's not like and can chip away at it, more so on his wheels.

Thanks,
Kevin
 
Pressure washer would be my first line of attack. Going to have to see it though. Plastic fender liners concrete really won't adhere to in such a way that it won't come off, but the bigger challenge isn't where it's thick, it's where it's thin. I'm thinking it's going to be a wheels off detail with heavy use of a pressure washer personally.
 
Add a steam cleaner and a tornador to your arsenal as well.
I had a similar problem, and I used everything I had, including a plastic knife.
It'll be a tedious job for sure.
All the best
 
Thanks for the advice.

I have a pressure washer, and other tools listed here.
I'll give it a go.

Yes, the wheels must come off.
 
Sugar water. Sounds goofy but i swear it works. Another geeker gave me that tip and I made alot of money from it

I'll have to give it a try, plenty of sugar in my shop as I love coffee.
How do you dilute it ?
 
I poured like a 4 pound sugar bag into bucket then kept adding water until it was like a thick syrup. Then I allied to concrete and the concrete melted away. Don't know exact dilution

Interesting, never would have thought sugar in solution was corrosive to concrete. Back Set seems to be a sugar, some surfactant, and detergent.

If you go the straight sugar route, you may want to heat it up or use hot water. I would think undissolved sugar crystals could be abrasive.
 
Sugar water. Very interesting, and good to know. Have to stow that one away in the bag of tricks, providing it works. Let us know how things turn out. Good luck.

Peace,

Darrin

I'll let you guys know how the sugar tip works come at the end of the week.
 
The Sugar sounds like a good idea if it works. I would use muriatic acid. We had a car in the shop years ago that was covered in concrete. Paint, glass, wheels etc..PLEASE TEST a small inconspicuous area first. Keep away from glass and any non coated metal. Dissolves concrete in seconds.
 
I know people that use Speedy-Clean Concrete Dissovler. It is not acid and works well according to the people that have used it. It is non-toxic and biodegradable.

The body shop next door to me gave me a gallon of some chemical that removes overspray that just melted the concrete away.
I'll look at the bottle today to get the name of it so I can pass it on to you guys.
This just just melted it, oily substance.
Safe for clear coats.

I sprayed it on the wheels and under carriage , I was shocked as to how fast it worked, easy money. :)
