and what is their #Basically, in out rental house, it looks like the guy dumped a bucket of motor oil on the garage floor and then used the oil to paint a section of the floor. And his car dripped everywhere on the other half of the garage. So now the while garage has drips of oil everywhere and looks kind of like the black parts of this freeway. And to make matters worse, it is totally soaked in to the cement.
I used degreaser on mine I found it at the automotive store. and than I hosed it down with a power washer.
if you want to clean it your self youneed to sprinkel tide soap all over the oil areas when it starts soaking the oil in the soap take a plactic brush and brush the soap around till the soap is dark then sweep it off and do the same process only with the soap a little wet with water kinda pasty with the plactic brush then rinse with a hose if possable when it is dry the oil will be gone, hope this helps.
