It appears that Clorox is seeking "new ideas for products that help consumers reduce the spread of bacteria, fungi and viruses that can cause illness. If a product concept is chosen through this campaign, the inventor will receive a $2,500 advance and other compensation based on sales."
However, "While submissions need not be limited to traditional home cleaning categories, Clorox is not interested in new ideas for personal care products, pharmaceutical drugs, or medical devices."
Full contest rules are available here.
Deadline is July 5, 2010, so get inventing!
