The only thing we used was a hot tub of soapy dishwashing suds and then rinsed with warm water and let them air dry. As far as I know, dear daughter never got sick from her bottles state of cleanliness. 
Personally, I would return it. You have to realize that germs are EVERYWHERE! Even the inside of your arm (which should be a relatively clean spot) has oodles of bacteria that can be cultured from a swab. Moreover, germs help us to get a healthier immune system - or so it is currently theorized at least
Will you be using glass bottles then? Glass is best - there has been all sorts of news out recently about plastic baby bottles being bad for baby too.
It sounds like more work than it's worth to me. A good specialized instrument to clean the inside of the bottle worked well for us at least.
Congrats on the pregnancy and hope you'll pop back in for the birth announcement!
