Why can I not take my rug to the dry cleaners? We will answer this question by showing you how the pH of your rug works.
There is no cookie-cutter or copy and paste solution to cleaning Persian, Oriental, or antique rugs. Authentic area rug cleaning is simply NOT the same as other, regular carpet cleaning services because each rug has specific wool, dye, and hand-knotted style that varies per rug and region where it was hand-made. That means every solution is unique to every rug.
Why You Need To Know pH of Your Rug
Understanding how pH balance affects your area rug is vital to achieving optimum cleaning results. Our generational expertise has given us an understanding of how pH levels differ for various types of soils, dirt, and stains and how these differences play a huge role in determining how your Persian, Oriental, or antique rug is to be properly cleaned.
Unfortunately, most local area rug cleaning services throughout Louisville and Lexington KY treat your rugs like any other carpet cleaning service and do not account for these factors.
This is fundamentally flawed and usually increases the damage to your fine area rugs over time. Deep within those half-cleaned rugs remains material that wears away at your fine rug’s fibers. In fact, we often have individuals coming to us after using another rug cleaning service that couldn’t get the job done right. Yikes!
Taking pH into account with our superior rug cleaning process protects your investment for generations to come and keeps the whole family safe.
How To Know the Perfect pH for Your Rug
In the world of area rug cleaning, understanding the pH scale is actually rather important to achieve optimum cleaning results. 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.
As you may expect, a high pH scale is a higher concentration, and a low pH scale is a lower concentration, or even an absence of hydrogen altogether.
pH is a logarithmic scale, meaning that as levels move away from pH 7 (neutral) there is an increase by an 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. 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 registers 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. 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 registers 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.
If you have children and pets or any sort of allergies, taking pH into account is a must for any area rug cleaning service!
The natural pH of most carpet fibers is near neutral (7). For wool, the natural pH will be between 5.5 and 7. For the life of the fiber and to keep from attracting soils, fibers are left as close as possible to their natural pH when the rug cleaning service is finished.
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. This choice helps protect the fibers and the color of the various dyes.
