The Quick Clean Micro Steam Bag is something that you can use in your microwave to thoroughly clean bottles, caps, pumps, and even pacifiers. It is much faster than boiling the water as you simply add a couple of ounces to the bag along with the parts and microwave it for 3 minutes. The bag steam cleans your parts and heats them well enough to kill almost any germs. The bag states that it kills 99.9% of most germs and bacteria and this is probably better than you could expect by putting the parts in the dishwasher. My wife uses them to clean the parts from the pump including the tubing, but we get the most use out of them for cleaning the pacifiers. A box of these contains 5 bags, and each bag can be used up to 20 times. There is even a place to check off the number of uses of the back of each bag to help you keep track. We found these at Target for $5.99, however they can be ordered from the Medala web site or found in numerous online stores. You can often find them cheaper online but the price is generally about the same when you factor in the shipping cost. These are great bags for cleaning and we have never had any problems with them. After use the bag is very hot so you will either need to let it cool for a bit or use oven mitts when removing it. It you have small kids these are great for killing germs and I would highly recommend them.
