In area rug cleaning, understanding the pH scale is actually rather important to achieve optimum cleaning results. Perfect PH for Your Rug. Sadly, many cleaners, even professionals, would admit that the pH scale isn’t exactly their idea of bedtime reading – so we’re here to help!

pH levels are a measure of intensity for soil and stains. Essentially there is a range from 0 to 14 to indicate the pH level of a specific fabric. New fabrics stand at a 7 or neutral pH level.  The ‘pH’ is an abbreviation of ‘potential of hydrogen,’ and the numbers on the scale represent the concentration of hydrogen ions in a water-based solution. So it’s quite obvious that a high pH scale means higher concentrations of hydrogen ions and vice versa.

The pH level is a logarithmic scale, meaning that as levels move away from pH 7 (neutral), there is an increase by order of magnitude of the power of ten. pH 0 and pH 14 are 10 million times more acidic or alkaline than pure water.

Here is the pH scale with corresponding pH levels 0-14.

Essentially pH levels indicate the relative acidity or alkalinity of a water-based substance or compound. Perfect PH for Your Rug. Acids contain more positive hydrogen ions, which causes a  corrosive reaction with various substances. Alkaline substances are called bases. They produce hydroxide ions and in high concentrations, bases can react caustically to other substances.

pH indicators measure a substance’s acidity or alkalinity on a 14-point scale.

PH of 1 to 7

Substances with a pH of lower than 7 register as acidic. A substance with a pH of 1 contains the highest concentration of hydrogen ions, making it the most acidic.

Each sequential decreasing number is 10 times more acidic than the number before it. Perfect PH for Your Rug. So a substance with a pH of 5 is 10 times more acidic than a substance with a pH of 6.

PH of 7

Substances with a pH of 7 or near 7, register as neutral. These substances do not fall under either acidic or alkaline.

PH of 7 to 14

Substances with a pH of higher than 7 register as alkaline. Each sequential increasing number is 10 times more base than the preceding number. So a pH level of 11 represents 10 times the alkalinity of a level of 10.

There is a range from 0 to 14 to indicate the pH level of fabric; new fabrics stand at a 7. It is important to understand that pH is a measure of intensity for soil and stains. Each pH level differs for various types of soils, dirt, and stains.

The majority of soils are acidic and average between 4 and 5 on the pH scale. Soils become much easier to remove when they are neutral. Alkaline substances mix with fats, oils, and grease and result in a soap! Large amounts of a buffering agent (alkaline builders) in a cleaning product cause pH to shift in a wool rug.

Immediately or overtime, this pH shift will result in your rug dye bleeding. Simply noting a cleaning product’s pH will not tell you if it has been highly buffered. One must check the stability of the pH.

This is done by a test carried out on the chemical. It involves a rather simple laboratory procedure known as titration, which you probably encountered in a high school chemistry class!


To sum up, once the type of fiber is known, our facility determines what type of soil is in your Persian, Oriental, or antique rug and the amount of soil present. Most soils on rugs are acidic, consisting of food, beverages, bodily fluids, etc. — all requiring a neutral to alkaline cleaner for removal. Rugs are usually made from all-natural sources, like wool, so a neutral or slightly alkaline chemical solution is often the best choice. Perfect PH for Your Rug.
