Continuous buildup of detergent in the dishwasher can result in a foamy white deposit remaining on your dishes at the end of the dishwasher cycle. It is not because of their purity that these dishes look like they have to go through another cycle! The answer lies in cleaning the dishwasher regularly.
Steps
Step 1. Locate the drain siphon
It sits at the base of the dishwasher and is called that for a reason! This siphon should be cleaned regularly to remove stuck food particles, dirt and even accumulated dishwasher detergents (especially bar or powder varieties).
Step 2. Clean the dishwasher by hand
Use a small brush to remove any remaining soap suds. Dip the brush into white wine vinegar to help loosen the limescale. Remember to clean all sides, racks, cutlery holder, bottom and lid of the dishwasher. Also wipe down the soap dispensers where a lot of sediment is likely to have accumulated. Stubborn soap bars can be cleaned with citrus or eucalyptus oil applied to a damp cloth.
Step 3. Place a large bowl of white vinegar in the dishwasher for testing
Place it on the lower level of the dishwasher and run the wash for a short time.
Step 4. Wipe down all surfaces of the machine after washing
Step 5. Test drive for cleanliness
Your next load of crockery should be shiny without any residue.
Step 6. Repeat the described cleaning process regularly to prevent the lather build-up
Once a month is ideal if you use the dishwasher every day; or every three months if you turn on the machine less regularly.
