To clean stained carpet, begin by blotting the stain with a clean cloth to absorb excess liquid. Use a carpet cleaner specifically designed for your carpet type, applying it according to the manufacturer's instructions. For tough stains, consider using a mixture of vinegar and water. Always test on a hidden area first to avoid discoloration.

Cleaning stained carpet is crucial for maintaining aesthetics. Key benefits include improved appearance and hygiene, while challenges may involve addressing tough or set-in stains. Regular cleaning and prompt attention to spills can prevent stains from becoming permanent.
