Very effective kettle descaler and dishwasher cleaner
April 7, 2017
This product is 100% citric acid. I purchased this to descale my electric hot water kettle and for use as a dishwasher cleaner. It does both jobs very effectively and has several advantages versus the other alternative most people use, which is vinegar. I will detail these below.
A citric acid solution, at the same normality, is more acidic than vinegar which makes it a more effective descaler. It can also be stored more compactly than a bottle of vinegar and is readily made into solution when needed. For use as a kettle descaler, I added 4 tsp (about 19 grams, 0.1 mole) to 1 liter of water, boiled it in the kettle and let it sit for 15 minutes. It completely dissolved a year's worth of mineral deposits. I then soaked the aerator of my kitchen faucet (which was partially blocked) in a small quantity of this hot acidic solution. It cleared it up very effectively, something which repeated overnight soakings in vinegar had failed to do. Aside from the effectiveness, another advantage is that, unlike vinegar, it has no odor and the kettle is more easily rinsed free of the acid after descaling. Needless to say, it is much more cost effective than buying a dedicated descaler, which is most likely citric acid, but with some snazzy brand name so they can charge a hefty premium for it.
It works very well as a dishwasher cleaner. An advantage it has versus vinegar for this application is that you can simply put a quantity (I use 2 tbsp) in the dispenser and start the wash. It will automatically get used during the main wash cycle which is when the dispenser door opens. Being the longest cycle of the wash, it is the most effective way of using a cleaner. To get the same effect with vinegar, you have to start the dishwasher, wait for the pre-wash cycle to complete, open the door and pour in the vinegar. This works, but is obviously less convenient.
This particular product itself is well packaged. I like the fact that it is resealable, which means I do not have to find a separate container for it. The granules flowed freely with minimal clumping. The two pound bag is a good size for my needs and should last me more than a year. Recommended.
