How to disinfect your dishwasher

The best dishwasher detergent and detergent for people with food allergies, says a new study by Consumer Reports. 

“There’s no question that we need to improve the way we disinfect our dishwashers,” said Dr. Robert Moulton, senior vice president of Consumer Reports’ Consumer Health and Personal Care.

“Dry cleaners are one of the easiest ways to do that.” 

Dry cleaning is the process of soaking or rinsing food, including fruits and vegetables, and then using an abrasive to scrub it off.

It is not an easy task. 

According to Consumer Reports, a dry cleaning process is about as difficult as it gets. 

In a dry-cleaning process, a vacuum cleaner removes dirt and debris from the dishwasher.

It then uses a machine to vacuum up the residue. 

When it’s done, the residue is left in the dish. 

However, the process can leave some residue behind, including food that has been exposed to air and bacteria. 

Some people with allergies have to use detergents that don’t contain any preservatives. 

There are products that don: clean the food with soap and water; add an ingredient to kill bacteria or fungus; remove grease from food and make it easier to eat; use an alkaline detergent to clean your food; or add a food additive to your dishwashing liquid. 

Dr. Moulson said that consumers are sometimes surprised to find out that they can’t use some of these products. 

While they can be a challenge to use, they do work, he said. 

To find out how to properly disinfect your kitchen and dishes, Consumer Reports tested all of the brands of dishwasher detergent we reviewed, including brands like Norelco and Tide. 

We then rated them on a scale of 1 to 10 for how well they do to help people with foods allergies. 

The products were scored using our new Comparison of Consumer Product Ratings (CCPR) algorithm, which measures the efficacy of products on the human body. 

It takes into account the number of ingredients in a product, the safety of the product, how it’s used, the amount of time it takes to use it, the length of time you can use it and whether the product will harm people with certain health conditions. 

For this study, we compared detergent brands based on their CCPR scores. 

Here’s how Consumer Reports found the top 10 best detergent companies: 1.

Norellco, All-In-One Detergent (100)  “This is one of our most popular products, and the best detergent for those with food intolerances, allergies or sensitivities,” said Elizabeth G. Lee, a senior scientist at Consumer Reports and co-author of the study. 

This detergent has the highest score of 0.9 on the CCPR scale, which means it can be used for cleaning foods with food that’s not normally contaminated by food and/or water. 

Lee said that it’s a good choice for people who have allergies to the ingredients in most of the products we tested. 

Norell was rated “1 of 5” for a number of reasons, including the fact that it doesn’t contain preservatives or additives. 

You can also use this detergent on other foods that are contaminated by your pets or other animals, and it’s safe to use on food with high amounts of gluten. 


Tide, Cleaning Detergent and Detergent with a Side (100/100)  “Tide’s Cleaning and Dishwasher detergants have great ingredients, and have proven to be the best for people,” Lee said.

Tide cleans foods with a detergent that’s non-toxic, non-sulfuric acid, and contains only water and sodium hydroxide. 


Natura, Cleaner Plus (100), 100% Free (100%) “The free-flowing water and salt in Naturas Cleaner plus detergent is great for removing grime, dirt, and oil from foods, including grains, beans, and nuts, Lee said in a statement. 

As a non-paregoric detergent with the highest pH score, Naturates Cleaner is ideal for use on fresh foods, especially with a wide variety of foods. 


Tide-Free, 100/50 “A 50% bleach detergent will remove grease, grease residue, and oils from the food without harming the food, so it’s an excellent choice for those who have food allergies,” Lee noted. 


Nootro, Cleanermate (100): 100%-Free “Nootro’s Cleanermine is a safe, low-pH detergent designed for people sensitive to chemicals in food,” Lee added.
