Simple Green to Clean Thermos

Both the Clorox Bleach company Customer Service and Oxiclean Customer Service say not to use their products to clean a stainless steel thermos. Why? Using products that contain bleach can cause damage to the metal. I contacted the company that makes "Simple Green" and was told that their product will not damage a stainless steel thermos.

Here is the email response from Simple Green:

Simple Green All Purpose Cleaner is safe and effective for cleaning the inside of a stainless steel thermos. The product can be used at about a 1:10 dilution ratio. To insure that there is no residue remaining, rinse thoroughly with clean water.

I was able to purchase Simple Green at Ace Hardware. It is likely that it is available at other hardware supply stores. And yes, it does work.
