Labware Cleaning: Solujet Leaving Ring

Q. It appears that the Solujet is leaving a ring on some of the labware that cannot be removed. What is this ring (sodium silicate?)? How do we remove it? The labware has not been completely submerged. We have just added the Solujet soak for some labware that may have stubborn organics. We have been giving the labware a 4 hour soak in 1% Solujet, followed by warm tap water rinse then wash with Liquinox followed by 3x DI rinse.
