To Wolfy and others, I used Citra Solv, which is a chemical-free, natural cleaner and degreaser that is safe for pets. It contains natural citrus extracts and biodegradable cleaning agents. It smells like oranges. I don't know if regular stores carry it; I bought it at a health food store that is very environmentally conscious. You can buy it in concentrated form and dilute with as much water as you like. It's ok for hardwood floors and can be used on carpets and upholstery. I make sure I dry it well with a paper towel before I let Rocky in the area. That's funny about the vinegar, that they mark it! I was considering trying vinegar. I wouldn't use bleach; I think the fumes are too toxic. Dooks & Happy Holidays to all Shron & Rocky [Posted in FML 5823]
