The pH of washing soda typically hovers around 11. However, this can vary depending on the brand and how much was added to the product. For example, some brands may have a pH of 9 while others may be as high as 12. If you are looking to clean anything dirty, there is a good chance that the cleaning product you choose contains washing soda. It is one of the most commonly used household cleaners on the planet.

But just how high does the pH of washing soda go? 

So what happens if you add too much washing soda to your cleaning project? Well, adding too much can cause damage to surfaces that are exposed to high pH levels. This includes things like wood floors and granite countertops. Moreover, when you add washing soda to your laundry load, the pH of the solution will rise. The higher the pH of the washing soda solution, the harsher it will be on clothes and fabric.

At a pH level below 7, solutions are acidic. At a pH level above 7, solutions are alkaline. Most laundry detergents fall into the alkaline category. They cause bright colors in your washer when they react with fabrics and remove dirt and stains. When you use too much washing soda, it can also cause build-up on your machines and leave behind a residue that is hard to clean.

There are a few ways to measure the pH of a substance, but the most common is to use a pH meter. When you mix washing soda with water, the alkaline wash will neutralize the acid in your detergent and leave behind a buffer solution. To measure this buffer’s pH, you can use a pH meter.

While high pH levels are not ideal for cleaning purposes, they have some advantages.

For example, high pH levels kill bacteria more effectively than low pH levels. Additionally, high pH levels help deter mold and mildew growth. Washing soda is a popular cleaning product that can be used in various ways. Many people use it to scrub toilets, clean windows, and bleach laundry.

What is washing soda, and what does it do?

Washing soda is a type of sodium carbonate used in many households as a cleaning agent. It can be found in most stores and made at home. When used as a cleaning agent, washing soda breaks down organic material such as dirt and oils. This process helps to remove stains and make surfaces clean. 

Accordingly, washing soda is a type of alkali. It is a white powder that can be found in most grocery stores. Washing soda is used as an emulsifier and detergent. It helps to break down the oil and grease that are on clothing. It also helps remove dirt, stains, and other impurities from clothes.

Why was washing soda pH tested? What does this mean for cleaning products?

Washing soda, also called lye or muriatic acid, is a standard household cleaner. Some people use it to remove oil and grease from surfaces. Washing soda is also used to neutralize acidic ingredients like buttermilk and vinegar. In either case, washing soda is diluted with water before use. When diluted with water, washing soda has a pH of about 11-12.5. This means it is alkaline and will attack oils and grease on surfaces. However, if washing soda’s pH becomes too high, it can damage surfaces and furniture. It’s important to remember that washing soda’s pH will change depending on your home’s temperature and humidity levels. 

The pH of washing soda is highly alkaline, with a pH of 12. 

Washing soda’s high pH can be attributed to its high potassium and sodium content. Washing soda is a popular household cleaner used as a pH adjuster. Many people are unaware of the high level of alkaline of washing soda. Washing soda high alkaline results from the presence of potassium carbonate. When potassium carbonate is combined with moisture, it forms caustic soda. This alkalinity makes washing soda an effective cleaner for many surfaces, but it also has potential dangers if not used safely. 

When using washing soda on delicate surfaces, test the pH before use to make sure it is safe for your specific surface. If you doubt the safety of using cleaning products containing washing soda, err on caution and avoid using them on delicate surfaces. 


In conclusion, the pH of washing soda can be vital because it can affect the cleaner’s effectiveness. Washing soda can be a great way to clean your household items, but it is essential to be aware of the pH level and how high it can go. The higher the pH level, the more acidic the wash. This can damage some materials if used excessively. So, be sure to follow the instructions on the product label and use caution when using washing soda.
