I think that this product works really well. It smells nice, and not much is needed to wash a sink full of dishes. It does a good job with grease.
I also use it as a laundry detergent. Ajax lemon is excellent for that purpose. One teaspoon for a small load, two for medium, and three for large. Using these amounts, it rinses out sufficiently. The clothes come out nice and clean and all stains are gone. The 16 ounce bottle lasts a long time as I average three loads a week.
