Your Couch is a Magnet for Germs, Sweat and Body Oils

The couch is one of the most frequently used pieces of furniture in many homes. It's where we relax, watch television, spend time with family and, in many households, share space with our pets.

But unlike clothing or bedding, upholstery isn't washed regularly.

Over time, upholstered furniture can accumulate sweat, natural body oils, dead skin cells, food particles, dust, pet dander and other everyday debris. Much of this contamination isn't immediately visible because it settles deeper into the fabric and cushioning.

Understanding what builds up in your couch — and why regular cleaning matters — can help keep your furniture cleaner, fresher and better maintained.
