The majority of stain complaints are actually soil related. For example, many sugar-based spills, such as soft drinks and coffee, leave a sugar residue after removal. This sticky residue readily attracts soil from ordinary shoe traffic, and the resulting discolored area appears to be a stain.
The same thing happens when spills are cleaned with a detergent solution and the area is not sufficiently rinsed with plain water, leaving a sticky detergent residue. It is important to rinse thoroughly with water and blot dry after removing any spill.
You will want to reference the manufacturer’s warranty for specific care requirements.
