According to Curtis E Carpets, “Browning is when the tips of the carpet turn dark. This issue is different than wicking and usually shows up as large, brown, blotchy spots. Browning occurs when there is high alkalinity in the carpet, sometimes from things that have gotten spilled into it. When properly diagnosed, this issue is easily resolved with a treatment that reduces the alkalinity in the carpet.” If you have browning on your carpets please call Triple D’s Carpet Cleaning at 910-273-3661.
