1 cup bleach, 9 cups water that is the ratio for restaurants for wiping down the service tables in the kitchen. As for felt soles, I switch over to ScotchGuard Pad for the bottom of my wading boots years ago, I wear slip-overs (in Minnesota we call them rubbers) for walking from and to the stream from the parking area, then remove them for standing in the water. I get home, I place my boots in a large bucket with the above ratio of bleach and water. So what exactly is the problem? ~Parnelli
