Common Types of Dishwasher Deposits

The most common types of dishwasher residues include grease, detergent, hard water scale, and streaking. Although your dishwasher is designed to manage these deposits, the lingering layer of unwanted residues are just not acceptable. Even if you have the newest, most innovative dishwashing machine model on the market, dishwasher residue is a possible issue to encounter. Fortunately, all dishwasher deposits are perfectly treatable, and best of all, most methods cost less than your average delivery pizza order!

Dishwashing Residues and How to Treat Them


Grease is a dishwasher’s biggest challenge, whether man or machine. Although modern dishwashing appliances are designed to breakdown and dispose of grease particles during a clean cycle, the oily remnants are bound to adhere and linger, especially if you cook with grease often. In isolated cases, such as a greasy turkey pan from Thanksgiving, the solution is to rerun the cycle a second time, then empty the dishwasher, place a cup of white vinegar inside, and then run it again on the hottest cycle.

If you are persistently dealing with grease residues in your dishwashing machine, it could be due to low-quality or incompatible detergent, or because your hot water is not hot enough. Lack of hot water can originate from your water heater or the dishwasher heating elements.


If you are not using the right kind of dishwashing detergent in your machine, you could run into some residue issues. Avoid phosphate-free dishwasher products, as these tend to leave behind the highest traces of residue after a cycle. If you already have the tell-tale white gunk caked on the inside of your appliance, some scrapping, scrubbing, and wiping will do the trick.

Streaking and Spotting

Although water isn’t technically, or evenly closely, a residue, it can still cause the outcome of a dishwasher cycle to be something less than desired. Dishes that never seem to rinse clean, or dishes with streaking or spots, might be the result of a poor-quality rinse aid, or lack thereof.

Hard Water Scale

Hard water is water that contains high traces of dissolved minerals, or mineral ions, like calcium, magnesium, and iron. These elements can cause water to deliver poor taste and performance, even with dishwashers. After some time, hard water forms limescale, which can come in an array of colors, like white, blue, and green. This scale is damaging to plumbing pipes, appliances, dishes, and more.

The best way to solve a hard water problem is to install a water softener. If you already have a water softener, you may require repair or replacement. To remove hard water staining, combine distilled white vinegar and lemon juice to form a cleaning solution. Scrub away and rinse with clean water.
