GB Tips to avoid stains and films: The following suggestions are recommended to prevent stains and films from dishware and utensils items: You must rinse all dishware, silverware, glassware and food containers right a way after use. Some citric based food products, coffee, tea and iron deposits in water can cause yellow or brown film on inside surface when left on for a long time and not rinsed immediately. You must check your water hardness to see whether you need to use more or less detergent to wash. If water is extremely hard then it may be causing stains on items. You may need to use water softener. Do not over load the dishwasher. Avoid improper loading. Make sure there is a proper water temperature that is recommended to wash dishware. Do not use too little detergent. Do not use old or damp powder detergent. Do not load aluminum utensils improperly. Aluminum utensils can cause gray or black marks to porcelain utensils if touching during wash cycle. 14
