The pH value is a measure of the degree of acidity in a solution, where low values indicate acidity and high values indicate basicity. Acidity is important to understand when cleaning, as different substances require different pH levels for effective cleaning. Acidic cleaning is effective against limescale, salt and rust, while basic cleaning is good against stains and dirt from the plant or animal kingdom.

The pH value of a soap is stated on the label and it varies between different soaps, manufacturers and brands.
What is pH or pH value?
pH value is a measure of how acidic something is. If you measure the pH value and get a low number, it means that what was measured is acidic. Lemon, vinegar , stomach acid, battery acid are acidic and have a low pH.
If you measure the pH of a tomato, coffee or rainwater, you will probably get an answer of 4-6. Tap water has a value of about 7.
Basic things, on the other hand, have a high pH. Apples, bicarbonate and milk are basic and have a high pH.
Now you have some references on the scale for pH values.
When it comes to cleaning, this is pretty important to keep track of. Why? - Well, that's how it is. If you know these simple things, acidic and basic, you can easily clean most things without having to use unnecessary chemicals.
You remove limescale, salt and rust with acidic agents - examples of acidic "cleaning products" are citric acid, vinegar or vinegar.
Stains and dirt from the plant or animal kingdom (most things can be counted here, all dirt that comes from ourselves, for example) you remove with a basic product such as soap, soaps are usually at pH 9 and above.
Grease, greasy stains are the easiest remedy with an over-greased soap . Equal solves equal, so an overfatted soap fits perfectly. Soap can be at a pH of 9 and up.

A low pH value indicates acidity. Examples of acidic substances include lemon, vinegar , stomach acid, and battery acid.
- What does it mean if a solution has a high pH value and which substances are basic?
A high pH value indicates basicity. Alkaline substances include apples, bicarbonate and milk.
- Why is it important to understand pH values when cleaning?
Understanding pH values is important when cleaning because different substances require different pH levels for effective cleaning. Acidic cleaning is suitable for removing scale, salt and rust, while basic cleaning is effective against stains and dirt from the plant or animal kingdom.
