1. Save money on dishwasher supplies by purchasing the least expensive brand of detergent/soap. Then just add a few tsps of white vinegar right into your dishwasher before running it--the vinegar cuts grease and is guaranteed to leave your dishes spot-free and sparkling!
2. To clean your dishwasher, place 1 cup of white vinegar (in a bowl or measuring cup) on the top rack. Run of full (empty) cycle on the hottest setting.
Also, placing 1 packet of LEMON Kool-Aid in the dispenser and running a hot cycle as works because of the citric acid in the powder.
These two remedies will definitely help if you deal with hard water in your home! :)
