Used couches can accumulate dust, stains and odours, yet you do not need a steam cleaner to refresh them. Start by vacuuming every crease and corner with a soft brush to lift out dirt particles. For spots, use a simple mixture of soap and water on water safe fabrics, or rubbing alcohol for solvent safe materials. Sprinkle baking soda to absorb odours, leave it for a while, then vacuum again. A mild solution of white vinegar, water and dish soap can clean without soaking. Finally, allow the couch to air dry and gently brush the fabric to revive its feel.https://www.endofleasecleanersmelbourne.com.au/clean-a-couch-without-a-steam-cleaner/
