Precautions
Wash ability Issues
•
Water
–
Too Soft (“oversudsing”) can leave deposits on clean dishes.
–
Too Hard can cause spotting/staining and poor wash ability
•
Dishes -- Too Dirty (garbage disposal), Too Clean (oversudsing) Thoughts? (Drain Suds Lock)
•
Detergent -- Chlorine, Enzyme, All-in-one & Tablets (oversudsing) Thoughts? (Suds Lock)
•
Rinse Additive -- Liquid in dispenser, All-in-one Thoughts?
Which Detergent Ingredients Give Best Dishwasher Performance ?
Detergent with a separate rinse additive in the dispenser gives better drying performance.
For tough baked on soils an Enzyme detergent is better at hydration of the food soils.
For staining such as tomato, coffee and tea, a detergent with Chlorine bleach will work on
the stains much better than an Enzyme based detergent.
Now that phosphate content in dishwasher detergent has plummeted to 0.5 percent from
as high as 8.7 percent, conditioned (soft) water is even more critical. The reduction of
phosphates may cause spots and film on dishes that can form when the minerals and food
bits combine during the wash.
It is important to test water hardness for wash ability
complaints.
