This COMBO will save you time, hassle, and potential mold issues—chuck all of the small feeding parts in the baskets and let your dishwasher do the work. The addition of the Valve CLEANER is ideal for those who are a little remiss when it comes to cleaning those hard to wash sippy cup valves. If you can relate, then it's best to let the valve CLEANER do the work as it shakes all of that caked on (and often moldy) milk and juice right off, allowing thorough sanitization. The BASKETS keep everything contained so you don't have to perform search and rescue operations at the end of a load. One set will last you a lifetime. Doesn't get much better than that.
