Zojirushi #CD-K03EJU Inner Container Cleaner for Electric Pots, 4 Packets

Absolutamente necesario para mantener limpia y funcionando la dispensadora de agua caliente Zojirushi. Recomendable.

Very good not to harsh

speedy delivery. worked perfectly to clean kettle.

I purchased this along with my Zojirushi CV-DCC50 hot water boiler/dispenser. Specifically because Zojirushi recommended only this be used, and it is made by them. This lasted one year's use. It works exceedingly well in removing/softening our TN hard water scale that accumulates on anything that holds or boils hot water, such as this, coffee makers, etc. Follow the directions in the owners manual, exactly, and you will get great results. Be sure to wear protective gloves and eyewear. Be very careful because you are handling mild, concentrated acid and boiling water. As well as an AC electrical connected appliance that is near water. We refill our boiler multiple times daily and must be vigilant in regularly descaling the pot. Made by Zojirushi for Zojirushi hot water pots. Only thing recommend by then for descaling. Great product by the maker of the best, Made in Japan, small electric appliances. Hands down!

Our water boiler had not been washed for many years. I put all 4 packets (4x30g) of the citric acid (dissolved) into the warm water in the boiler and reboiled the water and left it for 3 hours. The water becomes yellowish. After throwing away the water, I took the photo (see attached). The pot of the boiler looks clean as new (up to the maximum line). Excellent!
