Calgon In Dishwasher

Suppose your utensils come out of the dishwasher with some greasy or white layers of residue even after using a cleaning detergent. In that case, you might be experiencing the effect of hard water. To prevent this frustration and your dishwasher from jamming, you should try Calgon. 

Calgon is a brand of water softener that is used in cleaning processes. This water softener comes in powder, gel, and 3 in 1 tablet. You can use the product in your dishwasher or washing machine due to its excellent properties, which will be discussed throughout this article. 

Is There Calgon for Dishwashers?

You might think using a dishwasher detergent is enough for cleaning. But do you ever think about your dishwasher? Since we assume the dishwasher also gets cleaned up when the dishwasher is washing utensils, I am sorry to inform you that you might be needed a new dishwasher soon.

It might not be too late for me to introduce Calgon. Calgon is a softener that helps soften hard water with over 250 ppm. It also protects your dishwasher’s part from jamming due to limescale, dirt, and residue buildup. Calgon also prevents the heating elements in your dishwasher from failing due to the high concentration of salty water.

It is worth noting that Calgon is not a descaler with another function in your dishwasher. So how do you use Calgon in a dishwasher when using a detergent?

Should You Put Calgon in With Your Washing?

Calgon comes in three forms that fulfil the same purpose. However, you should use Calgon powder and Calgon tablet for your dishwasher. Put Calgon powder in one compartment at the top, a dishwasher detergent on another soap cup, and one tablet. Set your dishwasher in the cleaning cycle and start the dishwasher.

Your dishes will not have any residue caused by limescale buildup by the end of the cleaning cycle. Your dishwasher parts will be cleaned, and any foul odor will have gone.

Avoid using Calgon at the bottom of the dishwasher. The tablets will dissolve faster and are utilized during the prewash process only.

What Can I Use Instead of Calgon?

If your water hardness is below 250 ppm, you can use Borax. White vinegar will work miracles for your utensils if you cannot access Borax.
