Think I will use Clorox next time. Elaine, I have attended more Health and Safety classes then I care to count over the years. Did you know that Pine Sol will not kill most germs? It is good at covering the smells but doesn't get rid of the root cause bacteria. The two things that have been recommend and I have used is bleach and germicide. I use a germicide by Purina for the dogs. It is called Purina Odor Control. It has three different ammonium's (the best if four ammonium's but this one works fine) and a very pleasant smell. With both of these cleaners it is very important to rinse. Hope this helps. Kathi
