I found this informative article about disinfecting that has some recommendations about different products and methods to use....it was helpful to me so I thought I would share the website.

I was interested in the Novalsan which my Vet daughter can get at cost for me....but I actually found a website that is cheaper than she can get! My daughter uses it as a presurgical scrub. But I found it as a less concentrated solution for general disinfecting. One thing that appeals to me is you can spray it and no rinsing needed.
