What Does Sanitize Mean On A Dishwasher: A Deep Dive

In today’s fast-paced world, convenience and hygiene are paramount, especially when it comes to kitchen appliances. Dishwashers have become indispensable in modern households, and among their features, the term “sanitize” stands out. But what exactly does sanitize mean on a dishwasher, and why is it important? In this article, we’ll unravel the significance of dishwasher sanitization, how it works, and why you should care.

Understanding Sanitization

Exploring the Concept

When we talk about sanitization in the context of a dishwasher, we’re referring to a process that eliminates harmful bacteria, germs, and microorganisms from your dishes, utensils, and cookware. This goes beyond simple cleaning, as it ensures that the items you use for cooking and eating are not just visually clean, but also hygienically safe.

The Science Behind It

Sanitizing in a dishwasher involves subjecting the items to high temperatures during the final rinse cycle. This temperature is typically around 150 to 160 degrees Fahrenheit (65.5 to 71 degrees Celsius). Such heat effectively kills the majority of bacteria and pathogens that might linger on your dishes after a regular wash cycle.

The Importance of Sanitization

Protecting Your Health

The primary reason for using the sanitize feature on your dishwasher is to safeguard your health and the health of your loved ones. Harmful bacteria like E. coli, salmonella, and others can cause foodborne illnesses, leading to stomach discomfort, nausea, vomiting, and even more serious health issues. Sanitization ensures that these pathogens are eradicated, reducing the risk of contamination.

Food Residue Removal

Apart from the health aspect, sanitization also aids in removing tough food residues. Sometimes, remnants of certain foods can linger on dishes even after a standard wash cycle. The high-temperature rinse in the sanitize mode helps break down and remove these residues, leaving your dishes not only clean but also free from any potential allergens.

Using the Sanitize Feature

When to Use It

The sanitize feature is particularly useful when you’ve had items in contact with raw meat, eggs, or other potentially hazardous foods. It’s also recommended after washing cutting boards that have been used to prepare raw foods. Additionally, if someone in your household is ill, using the sanitize cycle can help prevent the spread of germs through shared dishes and utensils.

Compatible Items

It’s essential to note that not all dishes and utensils are safe for the sanitize cycle. Items that can withstand high temperatures, such as glass, ceramic, and metal, are suitable. However, plastic items might warp or get damaged in the high-heat environment.

FAQs About Dishwasher Sanitization

1. Is the sanitize feature necessary for every wash cycle?

Using the sanitize feature for every cycle isn’t essential. It’s most beneficial when dealing with heavily soiled dishes, potentially contaminated items, or during illness outbreaks.

2. Can I sanitize plastic containers in the dishwasher?

Most plastic containers are not safe for the high temperatures of the sanitize cycle. It’s best to handwash them with hot, soapy water.

3. Does using the sanitize mode eliminate the need for pre-rinsing?

While dishwashers are designed to handle some food residue, it’s a good practice to scrape off excess food before loading them. Sanitization isn’t a replacement for basic dish preparation.

4. Are there any detergents specifically for the sanitize cycle?

Yes, some detergents are formulated to work optimally during the sanitize cycle, aiding in the removal of bacteria and germs.

5. How often should I clean my dishwasher itself?

To ensure your dishwasher functions effectively, clean it once a month by running an empty cycle with a dishwasher cleaner.


In conclusion, the sanitize feature on a dishwasher is more than just a convenient option. It plays a crucial role in maintaining the health and safety of your household by eliminating harmful microorganisms and ensuring your dishes are thoroughly clean. By understanding how and when to use this feature, you can make the most of your dishwasher while prioritizing hygiene.
