The Shaker Bottle Cleaner - Portable Spongless Bottle Cleaner, Perfect for Cleaning Protein Shaker Bottles, Plastic Bottles, Stainless Steel Water Bottles - 12 Pack

Yes this stuff actually works! I use it in my metal protein shake cups as well as my water bottles. I have purchased this several times and I will buy more as needed in the future. A bit pricy but it works.

I absolutely love this product. I go through blender bottles throughout the day and they sit until I get home. This helps keep them clean and able to be used again quickly when needed. Highly reccomended.

It most definitely works and I am very glad I purchased this! However... I dumped the packet in and closed the lid to start shaking it then my baby started crying so I left to go get her then I got distracted and forgot about it. I heard a loud POP from the other room and ran in to find out had exploded all over the house. Ceiling, walls, sink, dishes, everything. It was easy to clean though ha. I've been vigilant in not letting it set inside my Shaker bottle and haven't had an issue.

couldn't ask for any btter

I use this product in my camping supply box to clean all our utensils and bottles. Works great and don't need to do dishes after I get back.

I purchased this having high hopes for it, even knowing that all the other reviews were shill reviews (all reviews on or about the same day praising it as 5 stars, and not a single verified purchase? come on! even the last 2 reviews (Philip and Clark W) are from two different people reviewing the EXACT same products other than this product rating them at 5 stars. Listen Wheyclean, if you're going to try to pump up your reviews, at least make a better attempt at it! But.... even knowing this, I was curious enough and still purchased it. That's how much I wanted to believe in this product).I drink protein shakes a minimum of 2x per day everyday, and even switched to glass bottles because I hated that Whey protein stink one gets on their bottle. You may wonder "Why use this at all if you have a glass bottle?" but the reality is, the cap isnt made of glass, and there are rubber gaskets and plastic caps that get the "smell" on it. After using it, I think its just "OK", its pretty grainy (which is not a bad thing, just an observation), but it didnt "wow" me at all as far as removing the smell or making me feel like my shaker was cleaner than say conventional hot water or using baking soda. For the amount I am paying per packet, it gets docked one additional star making it a 2 star product - I can appreciate the nifty packaging, and maybe its convenient, but I can see why people dont buy this in droves and no one at the gym really talks about this. Its a mediocre product at a premium price point.

Bought this product for my hydroflask bottles. Works as labeled, even when I leave liquids in the bottle for too long. The portability is really convenient.

Works and is very strong. Saved my favorite protein shaker.
