Chem-Dry. The process removes stains steaming cleaning couldn't touch. I first used them years ago when I was fostering dogs, and I'll never use steam again.

I like Chem Dry too. I've used them (and companies like them) and the steam method. Steam takes too long to dry, even if they swear it will only be 'four hours', if you have any stains at all, they'll use more water and those areas can sometimes still be wet the next day.

However, I do think that although Chem Dry is better with stains, I think that steam cleans more deeply in general.

So it's basically a tossup to me.
