See the photo to the left of a tea thermos strainer that had gotten very tea stained? The second pic is half the strainer submerged in Smart Soak (the foaming action is the oxygen lifting the tea stains away).  Photo three is the "after" photo.  The difference is stark!

One day he visited our shop and found me lamenting about how stained my fine mesh filters were.  He formulated Smart Soak and a week later we got to test is on those strainers.  It amazed us!  All our tea gear was made to look like brand new.  It is now used frequently at our shop and home.  The active ingredient is sodium percarbonate blended with a number of water conditioning agents used to prevent calcium scaling.  There are no fragrances, dyes, or mystery "blue crystals" in Smart Soak.
