Understanding the pH of professional carpet cleaning products is important because the pH can affect how effectively the product cleans and how safe it is to use. A carpet cleaning product with a high pH, for example, may be more effective at removing stains and dirt, but it may also be more likely to cause damage to the carpet or to the user if it is not used correctly. On the other hand, a product with a low pH may be less effective at removing stains and dirt, but it may also be safer to use and less likely to cause damage to the carpet or to the user.
It is important to use a carpet cleaning product that is specifically designed for the type of carpet you have and to follow the manufacturer's instructions for use, including any precautions or warnings. This will help ensure that you are using the product safely and effectively, and that you are able to get the best possible results.
