What is hard water?

Depending upon the region where you stay and where you are getting your water from, you could be getting either soft water or hard water. Hard water refers to the water, which has a high saturation of minerals in it. Hard water is the water which passes through chalk, limestone deposits or gypsum. As the water percolates through these, it picks up tiny particles and residue of calcium as well as magnesium sulfates, carbonates, and bicarbonates. It is this presence of calcium and magnesium, which make your water ‘hard.’ 

How does dishwasher detergent work in hard water?

Due to the presence of calcium and magnesium particles in hard water, soap often forms an insoluble substance called soap scum, which can be very difficult to clean and get rid of. When it comes to dishwasher detergents specially made for hard water, these detergents are specially designed so that they do not form this insoluble scum. Instead, they dissolve quickly in the hard water and help clean all your dirty dishes easily.

Why do you need to use a special dishwasher detergent for hard water?

More often than not, if you do not use a special detergent in hard water and simply use soap, you will find that your dishes look dirty even after you run a complete dishwashing cycle. The hard water deposits can deposit themselves on your dishes and prevent them from becoming clean, which is why you need to find a special dishwasher detergent if you have hard water at home.

The presence of hard water in your dishwasher can also cause a film, white spots, or even deposits on your dishes after a dishwashing cycle. To prevent these from occurring, you need to find a special dishwasher detergent which works well even in hard water.

How do you use a dishwashing detergent?

Dishwashing detergents have made life very easy for most people who own dishwashers at home. All you need to do is remove the individual packaging from a dishwashing detergent tablet, and place it in your dishwasher. You can even add a water softener along with the tablet if you wish to, as this often works better when you are dealing with hard water in your dishwasher. 

The tablets dissolve in the water and clean your dishes thoroughly so that you don’t need to re-wash them again. Simply remove your dishes and dry them once you use the dishwasher detergent!

How much dishwasher detergent do you need to use for one cycle?

The problem with using powder forms of dishwasher detergents is that you need to individually measure the quantity of detergent every time you run your dishwasher. However, the new and better dishwasher detergents come in tablet forms which are individually wrapped.

These individually wrapped packages contain precisely the amount of dishwashing detergent that you need for one cleaning cycle in your dishwasher, so there is never any wastage of the product. You also don’t need to worry about adding too much or too little of the detergent, as these come pre-packed with the specific quantity of dishwashing detergent that you will need for a single wash cycle! 

So what is the best dishwasher detergent if you have hard water supply?

It can be a bit tricky to choose the ideal detergent for homes with hard water. If you don’t pick the right one, you will have issues with limescale buildup and not properly washed dishes all the time. Lucky for you, we did our homework and here is what we chose:
