The dishwasher is a fantastic invention that simplifies and quickens the entire process of washing dishes. But sometimes, you need to hand wash your dishes, cutlery, etc., for numerous reasons, one of which is that some stains are too stubborn and well-baked onto the surfaces of the dirty dishes. Sometimes, you can only remove these stains by handwashing with powerful dish soap and scrubber. Another reason to hand wash dishes is that the dishwasher can destroy your cookware and cutlery over time.
Kirkland Signature Ultra Shine dish soap manufacturers do not test it on animals; its label states that it is cruelty-free and has never been tested on animals. This fact makes it a better option for people looking for cruelty-free dish soap. On the other hand, scientists test Dawn Ultra Original Scent dish soap on animals before reaching shelves and final consumers.

Differences Between Kirkland Ultra Shine Dish Soap and Dawn
Kirkland Ultra Shine dish soap and Dawn Ultra Original Scent dish soap have a couple of differences. Unless one considers what smell the dish soap gives off, how sudsy the dish soap is when used, how much soap should be used to achieve the best results and efficient washing, etc., one can easily ignore these differences.
Some of the differences between Dawn Ultra Original Scent dish soap and Kirkland Ultra Shine dish soap are as follows:
Different Ingredients Used in the Dish Soaps
Sodium lauryl sulfate (SLS) and sodium lauryl ethyl sulfate (SLES) are surfactants that companies commonly use in dish soaps. Both are present in Kirkland Ultra Shine and Dawn Ultra Original Scent dish soaps. Aside from these surfactants, Dawn Ultra Original Scent and Kirkland Ultra Shine dish soaps have entirely different components. These various ingredients set the dish soaps apart from each other.
While Kirkland Ultra Shine dish soap contains sodium citrate and sodium xylene sulfonate, Dawn Ultra Original Scent dish soap contains sodium chloride and sodium hydroxide. Kirkland Ultra Shine dish soap contains d-Limonene, a chemical with a lemon-like smell (this chemical contributes to the citrus scent of the Kirkland dish soap), but Dawn Ultra Shine dish soap does not contain this ingredient.
Different Levels of (Potential) Toxicity
Dawn Ultra Original Scent dish soap and Kirkland Ultra Shine dish soap are not entirely free of potential toxicity to the environment. Both dish soaps contain synthetic elements and ingredients that can be harmful to human beings and, by extension, the environment. Dawn Ultra Original Scent dish soap contains fragrance and dyes; fragrance can cause skin irritation to human beings and irreversible damage to aquatic life.
Unlike Dawn Ultra Original Scent dish soap, Kirkland Ultra Shine dish soap does not contain dyes. Kirkland Ultra Shine dish soap has a citrus scent, so it includes fragrances as harmful as those contained in Dawn dish soap. However, the potential toxicity of Dawn Ultra Original Scent could be more than that of Kirkland Ultra Shine dish soap, courtesy of the dyes that are present in the former but not the latter.

Some of these similarities are that you should use neither dish soaps in dishwashers (both brands produce dishwasher detergents that are different from their respective dish soaps), and they are biodegradable.
Neither Should Be Used with Dishwashers
You should never use dish soap, whether it be Kirkland Ultra Shine, Dawn Ultra Original Scent, or any other brand of dish soap, to wash dishes, utensils, or cookware in a dishwasher. These dish soaps are specially made to hand wash dishes, and they produce suds, unlike dishwashing detergent. If you use Dawn Ultra Original Scent or Kirkland Ultra Shine in a dishwasher, the suds from these dish soaps may leak from the dishwasher and, over time, damage the dishwasher.
Biodegradable
Dawn Ultra Original Scent and Kirkland Ultra Shine dish soaps are biodegradable dish soaps; both contain biodegradable surfactants. Surfactants, short for surface-active agents, are molecules in cleaning products (such as detergent) that bind water and oil together so that the soap can wash them away.
The surfactants used in Kirkland Ultra Shine and Dawn Ultra Original Scent dish soaps are biodegradable; they can decompose by microbial and bacterial action. Dawn Ultra dish soap is touted to be 90% biodegradable; it does not contain phosphate, making it safe for wildlife.
