<VV> HELP-Clean oil/auto. trans. fluid from concrete

[Taruffi57 at aol.com]

This is one year old, new concrete - only walked on by my own feets....and  
a few others.
My Pontiac has a "period" 365 days a year and has left me some sizeable  
dark stains.   I'll be coating the floor with epoxy or some other  sealant - 
whatever is good, and cheaper, and I want that to adhere  permanently.
 
Yeah, I have tried a couple of auto parts store varieties of concrete  
cleaners, but I'm looking for something with a little better results.  I  
figured you guys would know - since you seem to know everything  else.....   :-)
 
Recommends on coatings also appreciated.   Hopefully, other  alternatives 
to the SPEED TV advertised U-Coat stuff.
