Chuck – I want to let you know that you did not steer us wrong on the garage floor. Because of the cold weather, we weren’t able to clean it for some time. Today, we decided it was time to clean it. It was so bad that I thought it would never clean up. I used hot water and a little Dawn, as you suggested, and it cleaned up beautifully and easily. After using the Dawn solution, went back over it with clear water. It looks like brand new now. Thank you.
