For best results removing oil with your concrete oil stain remover, don't forget to use Pour-N-Restore® Oil Stain Remover with the V-notch spreader when removing oil stains from concrete in your garage or on your driveway. This product really really does get oil stains out of concrete. That's all I have used it for. It got out an oil buildup so bad I thought we were going to have to re stain the driveway. Its a great investment.
