Please tell me what name brand of polyutherane do I use that can stand cleaning with just water and vinegar. And also high traffic areas like the living room and kitchen. The one I use was minwax and it is starting to chip. And its starting to take the stain with it. This would be my second time putting the polyutherane on the floor (each time I applied six layers). I was wondering if there is something that commercial buildings use that I can buy as well. Please help! I currently have red mahagony as stain right now could that be the problem.
