Compact and comes with many!
I recently tried the Mom Cozy detergent blocks for the bottle washer, and I'm thoroughly impressed. These tiny blocks come in small, compact bags, making them incredibly easy to store and use. Despite their size, they pack a powerful cleaning punch, leaving bottles sparkling clean and free of residue.
I love how convenient they are – just pop one into the washer, and you're good to go. Plus, the fact that they come in bags with many blocks ensures I won't run out anytime soon. If you're looking for a hassle-free and effective cleaning solution for your baby bottles, these Mom Cozy detergent blocks are a must-try!

A Game-Changer for Breastfeeding Moms!
I was a bit skeptical about buying a specialized bottle washing block at first, but I'm so glad I took the plunge! The Momcozy Official Washing Block is a total game-changer for breastfeeding moms like myself. This product has made my life as a nursing mom so much easier and more convenient.
First of all, let me just say that this block is SUPER easy to use. It's simple to pop in a dirty bottle into the machine, and before you know it, your bottles are sparkling clean and ready for reuse. The block itself is also very compact and lightweight, making it easy to store in my nursing bag or diaper bag.
But what really sets this product apart is its ability to get out even the toughest stains and residue. I've tried other bottle washing methods before, but nothing compares to the effectiveness of this block. My bottles come out looking like new every time!
The best part? The Momcozy Official Washing Block is affordable and makes a great investment for any breastfeeding mom. Trust me when I say that you won't regret buying this product!

Amazing
The Momcozy Bottle Washer Tablets have been such a great addition to our daily routine. As a busy parent, anything that makes cleaning bottles easier is a huge win, and these tablets really do the job well.
They dissolve quickly and help remove milk residue and buildup from bottles, pump parts, and other baby feeding accessories. After using them, everything comes out clean, fresh, and residue-free, which gives me peace of mind knowing my baby’s items are properly sanitized.
I also love how convenient they are. Instead of measuring or dealing with messy liquids, you simply drop a tablet in and let it work. It saves time and makes the whole process much simpler, especially during those busy days and late-night bottle cleanups.
Another plus is that they seem gentle but effective, which is important when cleaning items used for babies.
Overall, these tablets are easy to use, effective, and a real time saver. I would definitely recommend them to other parents looking for a simple and reliable way to keep baby bottles and feeding supplies clean. I will absolutely be purchasing them again! ✨

clean well
These work great in the Momcozy bottle washer. They are small and easily fit in to the center spot of the top rack. I occasionally find residue left on the bottles or nipples, but it is usually an indication I need to run a clean cycle on the machine and not due to the washer tabs themselves.
