First Post: Concrete/Cement Dust Issue

[Eisen Hulk]

Greetings.



First off, I just want to say what a great site. I have been reading and researching now for over two months, and the amount of information I have picked up is incredible. Well done and :thx



Here is my issue. My friend has a 2005 Yukon, and he parks in his condo's parking garage. They are doing construction above ground, and there is a lot of concrete/cement dust that's hanging around. One day last week it rained, and the water mixed with the concrete/cement dust, then it leaked through the garage and dripped onto his Yukon. It has now dried and I can't seem to get it off. I've tried Sonus clay, but it doesn't really phase it.



Could you please help a newbie??? Thanks in advance!

vinegar is good for lime based deposits which is what a cement based material is.

I concur on the vinegar...try going to a coin wash that has heated HP water and try spraying it as well...

I can't vouch for it as I've never used it myself, but this product is specific for concrete:



Cement Remover



Good luck.

That stuff is $20 for a 32 oz. bottle.

Vinegar is $3.



Go with the distilled white vinegar you can find at your local grocery store. It works.

Distilled White Vinegar. Use in conjunction with a plastic razor blade for the thicker areas.

Many thanks, guys. We're heading to the grocery store now to pick up some vinegar. I'll let you know how it works.
