The most common type of stain in carpet is a grease stain. Grease can come from many sources, such as food spills and cooking oil. It is important to clean up any spill immediately to prevent permanent staining. 2 Another common type of stain is pet urine. Pet urine contains high levels of nitrogen, which causes the carpet fibers to break down over time. 3 Dirt and dust are also common stains that can be difficult to remove. Regular vacuuming and spot cleaning with a mild detergent or enzyme cleaner can help keep your carpet looking fresh. 4 Stains caused by certain chemicals, like paint and ink, can be more difficult to remove. Professional carpet cleaning may be necessary for these types of stains.
