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 formulated for hard water will soften the water, act as a powerful cleaner, and break down the residue and deposits, so that your dishes remain sparking clean. We hope our review of the best dishwasher detergents for hard water will go a long way in helping you choose the best one for your dishwasher.

Types Of Dishwasher Detergent For Hard Water

Before diving into the list, let’s have a look at the different types of dishwasher detergents for hard water so that you can make an informed choice.

  1. 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.
  2. 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.
  3. 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 and powerful formula, and deep-cleaning ingredients make them popular as they do an excellent job of cleaning dishes. However, as they are premeasured, they offer less flexible use 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?

Here are a few pointers you should bear in mind when choosing dishwasher detergents for hard water.

  1. Type:Hard water dishwasher detergents 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 detergent 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.
    Paula Tarling, an experienced domestic cleaner and influencer, says, “Cleaning dishes in a hard water area can often mean you need a stronger product to keep your crockery and glassware looking their best. Quality dishwasher tablets are a great choice for powerful cleaning and keeping your dishwashing sparkly and stain-free.”
  2. Ingredients: The best dishwasher-safe 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, break down residue, and remove hard water deposits so that your dishes are sparkling clean.
  3. 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 scent that is soothing. 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.
  4. Eco-friendly solution:  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 pods and tablets require less storage space and also use less packaging. Buying products that come in recycled or recyclable cardboard packaging is also a good option.
  5. 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 and one that acts as a water softener.
  6. No residue: No one wants white spots and residue on their freshly washed dishes which is caused by the density of hard water. Select effective 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, they can leave 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. Hence, you need to select one with superior corrosion resistance.

Frequently Asked Questions

1. Is considering the type of dishwasher detergent crucial?

Yes, it is important. For instance, if you use a mild and regular dishwasher detergent with hard water, you may get a poor result. Likewise, if you use a harsh chemical on your delicate utensils, it will damage them.

2. What kind of detergent do I need to put in a dishwasher?

This would depend on the kind of water and the utensil you use.

3. Do all dishwasher models use the same detergent?

No, not all types of detergents may be dishwasher-friendly. Use detergents that are specifically formulated for use with dishwashers.
