Suppose you are like me then you are attached to your old faithful truck. The only problem is that old trucks tend to leak here and there. Mine is like most and started leaking from the gearbox and made a massive mess in my driveway. Being that I live in an HOA community that’s a huge problem. I used many products with my powerwasher to remove the stain. I will not say it didn’t lighten up a little but it didn’t remove it. CHOMP Concrete Oil Stain Remover: Pull It Out was a game changer. I put the product on and spread it with a brush, let it dry and the next day the stain is gone or drastically lightened up. Some tough old stains might take two applications. then you can just brush it away and remove the rest of the residue with water or rain.
