We just moved into a new house a year ago, and at about that time, my son's bike dripped oil all over our new garage floor. I had tried kitty litter, detergents, etc - nothing got the oil stain all the way out.

Just last week, I tried a new product called Eximo concrete cleaner. It's a powder that your sprinkle on top of the stain, and just leave it there. It took about a week to work fully, but now my stain is gone, and the wife is happy!

I purchased the Eximo online from mycaf.com for under $20. Goodluck to everyone, let me know how it works for you!

 

It sucked, it didn't work for me. It made the stain bigger
