I bought this to clean the inside of the tube because I had some gatorade and it got sticky. The big brush worked fine. The "worm" brush is a pain to get through the tube if the inside is sticky like in my situation. The cleaning tablet worked alright but failed to clean up the Gatorade.

Bottom line: Don't put sweetened beverages in the CamelBak.

Got just the kit with the brushes, since I use a combination of baking soda followed by a couple of drops of bleach for cleaning. Seems like it wouldn't have been so hard to make the tube brush longer than the tube itself, but maybe that is just my petty complaint.

If you only use water in your camelbak bladder and are consistent in emptying it out when finished and air drying the bladder (with hose in a vertical position, bite valve open), you don't need a cleaning kit. I have at least 6 or 7 camelbak bladders (going back 4-5 years) and still have never had odor issues with any of them. My thought is this on storage: air dry completley then seal up (preferred); leave completely full with water (less preferred but greatly preferred to leaving a bladder mostly empty with a few oz. wetting the sides, allowing stuff to grow). My camelbaks have been on two combat tours and multiple training deployments and are still clean and growth-free. If you use gatorade or other non-water liquids and fail to rinse them with fresh water immediately upon consumption, you will need this cleaning kit.

Works...How bout a old hanger and Kitchen spoon to hold the bladder open. Baking soda and hot water.

This kit makes cleaning a resevoir easier than ever. I am very impressed of how easy it is to clean my 3L bag with the kit

I haven't used the cleaning tablets yet, but the new plastic pieces to help dry the reservoir are designed much better than what I had before (some sort of foldable plastic tree that fit inside; also made by CamelBak). The tube brush does the job, although it can be a little challenging to push the brush all the way to the end. I still can't get the tube to dry on the inside, especially when keeping it attached to the reservoir, as pictured in the instructions for this cleaning kit.

The drying tool and hanger work great and replaced my makeshift coat hanger setup. I have a Nalgene. My g/f has a Camelback and used the cleaner tools and said they worked great. PROTIP: On my Nalgene both ends pop off the tube, and I can tie a few knots in a paracord, dip it in some mouthwash, and pull it through the tube and it works like a charm. I believe Camelbacks have only one end that comes off, so you really need the brush.

Works well and better than rigging up the drying yourself which can lead to procrastination of drying the next time. My advice for cleaning the tube is to let the tube dry, drop some paracord through, tie a knot or two in the end, wet the knot and then pull the knots through the tube. Works like a charm on mine and doesn't 'scrape' out the inside like the kit brush will. Otherwise, awesome kit!

Works like a charm! The CamelBak Hydration Cleaning Kit does exactly what it says it does and really makes cleaning your bladder so much easier and efficient. No more rigging hangers and stuff to dry it and no more soap taste after. Effortless cleaning!

I don't bother using the cleaning tablets. Not E.P.A. approved and bordering on being removed from shelves according to a pal at REI. I just make sure to empty the bladder when I get home and dry out as much of the moisture as I can with cloth and the tube brush then hang it in front of an A/C vent. If anything this kit decreases the longevity due to the tube brush scraping out the interior coating of germ fighting polymers. You're really exchanging one fatality to the bladder for another kind of fatality. In general using the cleaning kit is more traumatic to the bladder system overall.

You're honestly better off sticking the bladder into a freezer set at 0 degrees to prevent any growth in what water wasn't poured out or dried out after use.

I left some Emergen-C water in my camelbak and didn't like the left over taste. The cleaning tablets got rid of that, and the tube brush was easy enough to use. The water tastes much better now.

if you have a camelbak, or any similar hydration system, you just have to have one of these or you will never get that nasty stuff ouf of the drinking tube! rinse well after use or you get a funky taste for a little while after.

To avoid ingesting the green slime left in your camel back from last month's trip you have to clean it out good. We've all done it: Retunred home from some epic adventure and tossed all your gear in a pile intending to clean it up tomorrow... after work... seriously... I'll get to it Tuesday... or Wednesday. The little hanger works great for drying. I tried to make one of my own using an old plastic hanger, but it doesn't quite spread the walls apart to allow it to dry properly. This is a good kit!
