me too then when the floor dries I throw either dirt or sand on it whatever I have laying around then sweep it up in a pile and spread it out again and again then throw it away and let nature take its course. as you travel over that spot it will go away without you tracking grease and oil all over. there you just cleaned the floor for $1 once a month or so we have to pull the comet out of the garage and sweep it all out, pick up all of the tools weve been searching for and couldnt find. next we hose out the entire garage then sweep out the left over water spots just so were not laying in a pile of dirt or old chunks of gaskets. since I have one of those bounce house blowers it doesnt take long to dry the floor after a good scrubbing.
I do mine twice a year... I take everything out of the shop...blow it out, wash the walls and floor down, squeegee the floor and hang the mav. back on the lift... post #18 http://mmb.maverick.to/showthread.php?t=71952&page=2
It's good stuff. I also use it in a spray bottle to clean up under the car. Squirt it on, let it soak for a minute, then spray away the oily mess with a garden hose.
