What natural methods can I use to remove Oil and Anti-freeze from my smooth concrete garage floor?”
Scarecrow, I’m not sure whether you would consider muriatic acid to be natural, but I have found that it removes any stain from my driveway. This product is available at OSH, Home Depot and any pool supply store. I suggest you dilute it 20 to 1 on your first application. Then, if the 20 to 1 does not work, try 10 to 1. On finished concrete, suggest you first try in an obscure location. Be very careful with this stuff.
