Surf Excel - Common sense

Hope you folks have noticed Surf excel's advertisement commonsense. As a person from marketing department, I just wanted to be in common sense list by trying surf excel with my top loading washing machine. My wife and I had a lengthy argument about this and she doubted about the validity of this ad and it would be full of marketing jargon. At the end of the argument, I decided to purchase the top loading powder and experiment it. Obviously, I obtained the same results of 50% purity which was similar to the normal surf excel. After that I tried with Ariel and it produced say around 70% purity. So my advise is please have common sense.

Thanks,
