Abstract
Methods of cleaning sugar evaporators with a cleaning composition comprising a sugar or sugar-moiety containing compound are disclosed. The methods are capable of improved scale and fouling removal from treated surfaces, including scale containing calcium oxalate, calcium dihydrogen phosphate, silica and/or other components from sugar evaporators. The methods reduce time required for scale removal without the need for highly alkaline cleaning compositions, elevated temperatures and/or mechanical force applied to the scale.
