The provided context from the search results does not contain specific instructions or methods for removing pet hair from a sofa. Therefore, this answer is based on general cleaning expertise.
There are several effective methods for removing pet hair from upholstery, and the best approach may involve combining a few techniques. A primary tool for this task is a vacuum cleaner equipped with an upholstery or specialized pet hair attachment. Go over the entire surface of the sofa, making sure to get into crevices and under cushions where hair can accumulate.
For hair that is deeply embedded in the fabric, a simple and effective trick is to use a damp rubber glove. Put on a standard dishwashing or cleaning glove, lightly moisten it with water, and wipe your hand across the sofa's surface. The friction and moisture will cause the pet hair to clump together, making it easy to pick up and discard. A dry rubber glove can also work well through static electricity. Similarly, a clean window squeegee can be dragged across the fabric to gather the hair into piles for easy removal.
For routine maintenance and quick clean-ups, a quality lint roller or a specialized pet hair removal brush can be very effective. Reusable pet hair removers that use a microfiber or velvet-like surface are particularly efficient at trapping and lifting hair from fabric. Finally, you can lightly mist the sofa with a solution of water and a small amount of fabric softener to help loosen stubborn hairs before wiping or vacuuming them away, but always test this on an inconspicuous area of the fabric first to ensure it doesn't cause discoloration.
