Defree PH With Nature Stone

PH (Power of hydrogen) is a measure of the activity of hydrogen ions (H +) in solution. It is expressed in a scale from 1 to 14. From 1 to 6.5 is acid, from 7.5 to 14 is alkaline. 7 is neutral.

Most natural stones are sensitive to both acid and alkaline detergents. The reason is the fact that most stones are classified as a hydroxide and as a natural alkali. Acid will corrode and burn most of the rock by decomposing its molecular bonds.

Alkali usually does not cause rapid damage to rocks. However, they will deteriorate the surface of the rock. Acid corrosion is not always the same as the value in the PH table

For example, substances with lower PH numbers are stronger acids. The action with PH 1 is usually stronger than PH 4. However, some acids with higher PH are stronger than acids with lower PH.

On the alkaline side, a substance with a higher pH will be more alkaline. Impact with PH 12 carrier is usually stronger than PH 9.

When using alkaline cleaners, do not use boiling water because it can create stronger alkali with the opposite effect.

Learning about PH will help select the type of chemicals used for stone. However, the main factor to remember when choosing stone cleaners is the activity level.

For example: Most detergents have a pH of 7, however, some neutral detergents are stronger than others because they have a higher level of activity. There are many neutral detergents that do not work well to remove surfaces with small holes. There are also plenty of neutral detergents that overdo it with respect to the rock’s tolerance.

Many neutral detergents with high levels of activity often erode stone surfaces. Neutral detergent with a suitable range can be used on all stone surfaces if used properly.
