Ways to whiten teeth at home?

Any good ways to whiten teeth at home? Thanks!
--------------------
I found this article about the different teeth whitening ways. It explains the pros and cons of each one. http://the-dental-makeover.com/whiten-teeth-to-promote-confidence/cheap-teeth-whitening-methods/ I used Titanium white. I got a trial kit, used it at home and I am very happy with the results, (you only pay for shipping $0.99 , so it is cheap too ) If you want to try, here is where I got my coupon http://the-dental-makeover.com/free-trial-teeth-whitening/
