BIZ Stain & Odor Eliminator

My toddler really put BIZ to the test. And I was actually impressed with it. It got out blood, chocolate and red food coloring. I like that it's liquid; I always use liquid detergents. I feel powder doesn't dissolve particularly well and, thus, doesn't wash out as well. I liked that it can be used as a pre-treatment, additive, or detergent. However, I couldn't see the lines inside the cap to measure it.
