What Does Sanitize Mean on a Dishwasher

In today’s fast-paced world, dishwashers have become an indispensable part of our daily lives. These appliances not only save us time and effort but also ensure that our dishes are clean and safe to use. One of the features that you might have noticed on your dishwasher is the “sanitize” option. But what does sanitize mean on a dishwasher, and why is it essential? In this article, we’ll delve into the details of dishwasher sanitization and its significance.

Understanding Dishwasher Sanitization

Dishwasher sanitization refers to a specialized cleaning process that eliminates harmful bacteria, germs, and pathogens from your dishes, utensils, and glassware. This process ensures that your tableware is not just visually clean but also free from any potential health hazards. It’s a crucial feature, especially when you consider the hygiene and safety of your family.

How Does Sanitize Mode Work?

The sanitize mode on a dishwasher employs high temperatures during the final rinse cycle. This elevated heat level, usually around 150-160°F (65-71°C), is hot enough to kill most bacteria and germs effectively. The combination of hot water and high heat ensures that your dishes are not just clean but also sanitized.

Why Use the Sanitize Option?

  1. Health Benefits: Sanitizing your dishes can help prevent the spread of foodborne illnesses. Bacteria like E. coli and Salmonella can linger on improperly cleaned dishes, leading to health issues. Sanitization ensures that your dishes are safe to use.
  2. Enhanced Hygiene: Sanitizing is especially crucial for baby bottles and utensils. Ensuring they are germ-free is essential for your child’s health and well-being.
  3. Allergen Removal: For individuals with allergies, the sanitize option can help remove allergens like traces of nuts or dairy, providing added peace of mind.

When to Use the Sanitize Option

It’s not necessary to use the sanitize option every time you run your dishwasher. Reserve it for specific situations:

  1. After Handling Raw Meat: When your dishes come into contact with raw meat or poultry, it’s advisable to use the sanitize feature to kill any lingering bacteria.
  2. During Flu Season: Using sanitize mode during flu season can help minimize the risk of spreading germs through shared utensils and dishes.
  3. Baby Bottles and Pacifiers: Always sanitize baby-related items to protect your child from potential harm.

Tips for Effective Dishwasher Sanitization

  1. Pre-Rinse: Scrape off excess food but avoid pre-washing dishes. Modern dishwashers work best with some residue.
  2. Load Properly: Ensure dishes are spaced out for proper water and heat distribution.
  3. Use Detergent Wisely: Use the recommended amount of detergent to avoid residue buildup.
  4. Regular Maintenance: Clean your dishwasher’s filter and spray arms periodically to maintain its sanitization efficiency.


In conclusion, understanding what sanitize means on a dishwasher is essential for maintaining a clean and safe kitchen environment. This feature goes beyond cleaning; it ensures that harmful pathogens are eliminated, protecting your family’s health. Remember to use the sanitize option when needed, follow proper loading and detergent usage guidelines, and maintain your dishwasher for optimal performance.
