Never tried it since I don't care for detergent additives and I think it is full of surfactants. The Clorox web site says that only Clorox regular bleach is a registered disinfectant so don't expect to extra germ protection from Ultimate care.

...so I never use anything with chlorine. It was enough of a mess when the last washer's pump sprung a leak. I'm still a little afraid to use anything stronger than oxy cleaner.
Works well, but very expensive, good if you are worried about spilling bleach, or getting chlorine stains on carpet in the vicinty of your washer.
