The PH value of the cleaner is of utmost importance. Every mfr has to understand what PH is and how to check the PH value. You can get yourself a PH strip from the laboratory chemical supplier store.
The PH strip consists of a range of values from 2 to 12.5 with different colour patches. each colour patch represents the corresponding PH value.
So when u dip the PH strip in the liquid u would be able to know the PH value of the liquid.
The range from 2 to 6 is acidic in nature (with 2 most acidic and 6 slightly acidic)
The value 7 is considered neutral and balanced (i.e. does not harm the human skin)
The range from 8 to 12.5 is considered alkaline (with 8 being slightly alkaline and 12.5 very alkaline)
We will be coming across the PH in our everyday products which we use. The PH value of the products mfrd should be correct to get the correct efficancy of the product.
