Clorox Laundry Sanitizer, Unscented, 42 Fl Oz

Do you need to hold your rinse cycle and let it soak for so many minutes like you do with the competition? Please and thank you

picture is of "odor eliminator" but description of "laundry sanitizer". Sanitizer is not "unscented" so what is the actual product being sold?

why is this 3 times as much money then in the stores?

Is this price for one bottle?
