Descaler for Momcozy & Baby Brezza Bottle Washers
$18.99Free U.S. shipping
Unopened bottles: 30-day returns.
Full product description
A liquid citric acid descaler for baby bottle washers. It helps remove the white mineral scale that hard water leaves inside machines from Momcozy, Baby Brezza, Grownsy, Papablic and others. One 6 fl oz bottle of 50% citric acid concentrate gives up to 72 maintenance cleanings. Made in the USA by Think Crucial.
How to use it
- Measure the descaler amount your bottle washer's manual calls for.
- Run the machine's cleaning or descale cycle as its maker describes.
- Rinse thoroughly with fresh water before the next load of bottles.
What's in it
Citric acid, as a 50% liquid concentrate. Unscented and bleach-free. Because it's a liquid, there are no tablets to dissolve and you can use a little more for heavy scale.
How many uses will I get?
Up to 72 maintenance cleanings per bottle. Hard water, heavy buildup or a bigger dose means fewer.
Do I need to rinse after descaling?
Yes. Rinse thoroughly with fresh water before you wash bottles again.
Does it work in milk warmers?
It's made for bottle washers and other water-based machines, including milk warmers. Follow the warmer maker's descaling steps.
