You don't want harsh chemicals anywhere near your baby and his feeding supplies, but you don't have the counter space for a traditional bottle sterilizer, either, so how can you ensure everything is squeaky clean? The Munchkin Steam Guard Microwave Sterilizer is a safe, natural and efficient way to kill up 99.9% of bacteria on bottles, nipples, pacifiers, teethers, small toys and breast pump accessories right in the microwave. There's enough room to sterilize up to 4 baby bottles and 2 breast pump shields at once. This compact baby sterilizer fits all standard microwaves and works with both regular and wide-mouth bottles. The locking tab is designed to safeguard everything inside and prevent accidental opening, too. Baby-safe cleaning should always come this naturally.
