I messed up and put a greasy cooking grid on some cement pavers on our semi-new patio and it left a stain that doesn't come up with a close range power washer. Needless to say, I'm upset. My wife is upset as well. Very.
I've googled a couple things, but all I can see is industrial, parking lot cleaner for oil stains. Can anyone help me?
