I have used a 2% chlorine dioxide solution for about 10 years. I have used this product to clean snake tanks and bird cages, as well as the ferret room floor (linoleum), cages and food dishes. I have never had any problems. Best of all, no rinsing is required, although I do rinse the food dishes. Similar products are available elsewhere, but I have always purchased mine from a bird product distributor called Avitec.
