Great question.  Here are a few bullet points I send to my buyers:

•	Rinse your tank: It is very important to rinse your tank; additionally drying is even better.  The sooner you wipe off standing water especially when it contains cleaning chemicals. After wiping tank down, air dry the tank. This procedure will allow oxygen to dry your tank which will help maintain the protective film. 
•	Use proper tools: Use non-abrasive tools when cleaning your tank. Example soft clothes, plastic scouring pads. Do not use steel pads, wire brushes or scrapers.
•	Treat your water: Softening hard water can reduce deposits in your tank. Certain filters that can be installed to remove distasteful and corrosive elements. Contact a water specialist to insure proper water treatment. 
•	Always keep your food equipment clean: Clean your tank frequently to avoid build up, stains and contaminations. Using alkaline, alkaline chlorinated or non-chloride cleaners are recommended. Avoid cleaners containing quaternary salts. Boiling water or heating cleaners that contain chlorides will cause damage and corrosion to your tank. 
•	Regularly restore/passivity (film-shield) stainless steel.  
•	Remember - RUST starts with pits and cracks.

Anytime you receive new stainless equipment (including beer kegs), it should be cleaned and passivated.  Then you should also re-passivate them periodically.  In my brewery, we passivated every tank and kettle every 4 months or so.

If they are brand new, don't forget to clean them very well then passivate them.

Cleaning of rust from stainless steel water tank is not a very tedious  process.  At the time of cleaning, you must have citric acid powder, warm water, container, brass brush. For safety purpose you must have rubber gloves. 
When you start cleaning the tank, it must be dried up. Then scrub the rusty part with citric acid powder with the help of brass brush, it will help to eliminate the rust from the affected area.  Follow this process in other parts also, where you see rust. When all rust is cleared, then clean the tank with utensils cleaning soap and then apply open water. This whole process will solve your purpose. http://www.greatbasinindustrial.com/industrial-tanks-and-storage
