IN THIS ARTICLE

At some point, it has happened to all of us一 you load your dishwasher, run the wash cycle, and open the door to see that your dishes don’t look particularly clean. You repeat the process with the same result. There are water spots, white stains, and a cloudy film, especially on your glassware. All this is because of the hard water of your water supply which takes a toll on both your dishes and dishwasher.

Hard water contains a high quantity of minerals, especially calcium and magnesium, that leaves a residue on appliances and dishes. Using a dishwasher detergent specifically designed for hard water will soften the water and break down the residue and deposits, so that your dishes are sparking clean. We hope our review of the 11 best dishwasher detergents for hard water will go a long way in helping you to figure out the best one for your dishwasher. But before that, let’s have a look at the different types of dishwasher detergents for hard water so that you can make an informed choice.

Types Of Dishwasher Detergent For Hard Water

  • Gel detergents

Similar to dishwashing soap, they dissolve quickly, are less abrasive, are ideal for delicate dishes, and are the most budget-friendly choice. Unfortunately, they have the least cleaning power because they don’t contain enzymes and bleaching agents as these ingredients don’t blend well in a liquid.

  • Powder detergents

Powder detergents are yet another cost-effective option and clean well as they have a combination of enzymes and bleaching ingredients. They are often more effective than gels in cleaning dishes, and are ideal for homes with very hard water as it doesn’t come premeasured, so more detergent can be added if necessary. But using excess powder detergent can leave some residue. Also, powder absorbs moisture and may clump during storage. As the ingredients of powder detergents are activated by water, this would affect its cleaning performance.

  • Single-load tablets or pods

Tablets are in the form of a concentrated dishwashing powder, while pods usually come in the form of gel packs. They are premeasured and are directly placed in the dishwasher, so there is no requirement of measuring, or chances of spilling. Their easy storage, concentrated formula, and deep-cleaning ingredients make them very popular as they do an excellent job of cleaning dishes. However, as they are premeasured, they have less flexibility than powders and gels. Also, you need to ensure that your hands are dry while handling them, or they can start dissolving.

How To Choose The Right Hard Water Dishwasher Detergent

  • Type

Dishwasher detergent for hard water can be in the form of powders, gels, and single-load pods and tablets. Powders contain enzymatic and bleaching ingredients, and are very effective in cleaning dishes till they are sparkling. Gels are very budget-friendly, dissolve well in water, and are less abrasive, but not as effective in cleaning as they don’t contain bleach or enzymes. Single-load pods or tablets are a more expensive option and have less flexibility than powders and gels, but they have deep cleaning additives, concentrated formula, and an easy-to-store design.

  • Ingredients

The best dishwasher detergents for hard water would usually have citric acid, sodium-based ingredients, and several enzymes. Sodium citrate and sodium carbonate react with and replace magnesium and calcium ions which harden water and leave behind residue. Citric acid binds with the minerals in hard water to naturally soften it. Enzymes dissolve food particles and stains stuck on dishes by breaking down fats, proteins, cellulose, and starches, so that the water can easily wash them away. Together, these ingredients soften the water and break down hard water deposits so that your dishes are sparkling clean.

  • Scent

Dishwasher detergents come in a range of scents which are either naturally or chemically derived. This is not a priority with many as the scent doesn’t linger on the dishes. Most dishwasher detergents have a fresh and clean fragrance. Some have essential oil fragrances instead of chemically derived scents. Unscented options are also available and are a sensible choice for those who are allergic to scents.

  • Eco-friendly

If you are worried about yourself and the environment, eco-friendly dishwasher detergents cause less harm as they contain natural, biodegradable, and plant-derived ingredients. They not only clean your dishes well but also have less impact on the environment. Some dishwasher detergents don’t use phosphates which can damage ecosystems, and use enzymes instead. Dishwasher detergent tablets and pods offer the most concentrated and compact option as they require less storage space and also use less packaging. Buying products that come in recycled or recyclable cardboard packaging is also a good option.

  • Cutting power

Your dishwasher detergent should be powerful enough to remove spots of grease oil and grease in detergent. Choose a detergent that has a higher molecular level than the molecular level of the hard water.

  • No residue

No one wants white spots and residue on their freshly washed dishes which is caused by the density of hard water. Select dishwasher detergents that have a higher molecular density to that of your hard water supply.

How Does Hard Water Affect Dishwashers?

When water passes through soil and rocks, it picks up minerals like calcium and magnesium, which is what makes your water hard. It creates a limescale buildup in the connecting pipes and dishwasher when these minerals get deposited in your dishwasher. It also leaves a white coating, spots, or marks on dishes. Hard water contains metals like iron, copper, arsenic, and lead which react to air and cause corrosion.

This damages water valves, reduces water flow, and creates leaks in faucets. It forms rust in the dishwasher, a small amount of which gets transferred to the dishes. As rust increases, it starts falling which causes clogging and the dishwasher stops working. It creates interruptions in the water flow, increasing the likelihood of air being introduced in the plumbing system.

Hard water can make it difficult to clean clothes, dishes or take a shower and feel clean. Over time, it leaves behind a deposit, never promising a squeaky clean experience. This is when investing in a good-quality dishwasher detergent exclusively formulated for hard water help. These detergents prevent your dishes from having water stains and white deposits. In addition, you can look for bleaching and enzymatic agents in your detergent as they offer excellent cleaning by tackling hard water. Dishwasher detergents for hard water are available in many forms, such as gels, powders, single-use pods, and tablets. When you buy a pleasant-smelling detergent that leaves behind a clean fragrance, it will effectively eliminate any food smell from your dishes.
