Hi Kelly, thank you for your review. I'm sorry to hear about your recent experience using our Granite Grip, and I understand how frustrating this must be. Please know it is our goal to provide a solution to all our customers to help them fix their issues. With that said, we always encourage our customers to reach out to us directly for one-on-one service and to further help with their projects. In the meantime, I recommend using a concrete cleaner and stiff bristle broom brush on the surface to help remove these stains. Once dry, apply another coat of Granite Grip following the spread rate. Customer satisfaction is important to us, and we appreciate your feedback. Our Customer Care team is available and ready to help. Please contact us so we can assist. - Randy
