How to keep your teeth clean and white for $30-40 in year and feel great

I like strong tea and sometimes can drink it all day around, so no surprise that yellow teeth, stains and calculus became lately my big problem. I've spent a lot of money for regular, deep teeth cleaning. I've tried to cut cost by traveling to Mexico, which is 60 miles from my city and they do great one hour cleaning just for $30-40, but situation there has been deteriorated in last couple of years and now it's quite easy to loose there all your teeth or even more.

So I started looking for a new, sufficient and cheapest way to clean and may be whitening my teeth so I won't be forced to spend every year $100-140 for quality teeth cleaning and many hundreds for whitening in dental offices.

I don't have any medical degree and no knowledge in dental areas, so I was just a regular guy looking for a reasonable solution, but my MS in physics was helpful in the planning and performing this research.

I've tried different whitening toothpastes, teeth whitening substances from Scope, Act, Crest and many more without much success.They helped for sure to remove or discolor fresh stains, but didn't remove heavy brown calculus, yellow teeth. After wide Internet researches and many, many tests I've found my magic recipe, which made my teeth perfectly clean and look naturally as they should.
