Hey everyone. I messed up and accidentally dumped a boatload (4qts) of use oil on my concrete driveway. Well, I really forgot it was behind my car, and backed it out of the garage. This happened 2 days ago. I’ve thrown down Purple Power and scrubbed the concrete with a brush, and it has improved, but it’s not enough. Power washing didn’t help at all. I’ve watched 10,000 videos with several potential answers, but I’d like to hear what has worked for you. I like the idea of using a blowtorch to burn it out, but that will take days. Without spending a ton of money or having to dress like Heisenberg, how can I remove the stains?
