Of all the places I was able to find a cleaning kit for my Camelbak, it was in an El Corte Ingles department store in Spain during my holiday. It was refreshing to find such a specialized item in a big department store. In the Philippines, you would have to scour the bike shops all over Metro Manila to find one (if you're lucky). But here, since they do cycling and the outdoors more, it's easily available.
I was fooled by the huge box because inside the Camelbak Antidote Cleaning Kit are just two brushes (one for the bladder and one for the tube), two cleaning tablets, a small hanger (this attaches to the bladder via the quicklink), and a pair of extra bladder clips (?) to make them stay open. That's it. There are no instructions on how to use them, so I had to go to YouTube to see how it's done.
When I cleaned my hydration bladder last night, I realized that the most important part of this purchase is the tube brush. As for the rest, I can use regular household items. With the huge Omega port, I can actually put my hands inside to clean it with a sponge and soapy water. I didn't feel the need to use the cleaning tablets because it wasn't that dirty. I can use hanger with a clothespin to hang it to dry. That's it.
If you're looking for something to clean your Camelbak bladder, you can save up and just buy the brushes instead.
