Dishwasher: Treat for scale build-up

Routine Care

Treat for scale build-up

Removing the deposits from your dishwasher’s heating element improves the efficiency of the heating element and improves the appearance of the inside tub.

Timing: Every 2 months: February, April, June, August, October, December (yearly)

How To

Over time, a heavy film build-up from hard water minerals can become deposited on the inside walls and heating element of the dishwasher. After removing all of dishes, pans, silverware etc. and with no detergent in your dishwasher, the following should be done to remove the type of scale shown:

Mold: Place one tablespoon of bleach in your dishwasher and then run it for a full cycle.

Rust: Place about half of a small container of Tang brand orange-flavored drink mix and then run it for a regular cycle. The citric acid in the Tang helps to loosen hard water deposits and cleans the scale from your dishwasher.

Stains: Place a cupful of white vinegar in your dishwasher and then run it for a full cycle. An alternative to vinegar is baking soda


The benefits of this task are moderate. Doing this task can help maintain the performance of your dishwasher, and extend its useful life.


The cost of this task is low. It is estimated that this task should only take about 30 minutes to complete, and the task is relatively easy to do. No specialized tools are required, but you will need to have bleach, Tang brand beverage mix, and either vinegar or baking soda on hand.
