Lab Glassware Cleaning: Liquid or Powder Detergent in Washer?

We have purchased Detojet and have been using it straight out of the bottle into our dishwasher cup thinking it would get diluted in the dishwasher as it mixes with the water during the wash cycle.

You put the Detojet® Low Foaming Liquid Detergent, undiluted, directly into the dosing cup. Most cups will be sized to dose something like a 0.5%-1.0% detergent concentration relative to the amount of water used in the wash cycle. However, for scientific cleaning using a household dishwasher, we recommend using a powdered detergent.
