The concept of the dishwasher is to get clean dishes without having to scrub them in the sink. But if you've often found yourself opening the dishwasher to reveal dirty dishes after running a load—it might be time for you to change your dishwasher detergent.

Dishwasher detergents come in three different types, gels, powders, and tabs or packs. Choosing a detergent depends a lot on personal preference but there is a difference between the various formulas. Gels are amongst the least expensive but can be the least effective because you can't have a bleach and enzyme agents together so they might not clean as efficiently, but they can work well in humid environments where powder might clump. Powders, which are great for hard water have all the cleaning power you need but they can clump over time and filling up your dispenser can be troublesome. Tabs and packs pack a powerful punch that doesn't need any measuring and often has a rinse aid included but you pay a premium for the convenience.

Whatever your cleaning needs, here, the top dishwasher detergents.

    Water quality often varies depending on your location. In certain places, hard water, filled with higher concentrations of minerals, can affect cleaning results whether you are washing dishes, clothes, or even yourself. Since most dishwashing detergents are not designed to remove these minerals, you will need a specialized cleaning solution to get the water as soft as possible for the best results (re: less spots!).

    Adding the Finish Hard Water Booster is like adding a little extra cleaning fuel to your dishwasher. Meant to be used in tandem with other dishwashing detergents, this booster is focused on tackling the stains that commonly form in water filled with minerals like limestone and chalk. You can dispense the booster into a pre-fill chamber or directly into the bottom of the dishwasher.
