Several people have mentioned using bleach. May I remind you that bleach is a toxic agent??? Not safe to breathe in the fumes, not safe to get on your skin, and a host of other issues. A good H202 cleaner will do all the same things but wont be dangerous for you, your children or your pets.
Cutegirl had some nice ideas but, in my humble opinion, I think all of it is carrying the "green" thing too far. There are many great all purpose cleaners that are totally safe, smell great and do the job. In other words, if one uses all cutegirls tips, it would be a bit obsessive-compulsive and waste your precious time.
