Wash your faux leather furniture with a mixture of soap and water.
Rinse the furniture with a damp cloth and dry the furniture completely. In some cases, this may be enough to remove the rubbery smell from your faux leather furniture. If not, you may need to do further deodorizing.
Mix one part white vinegar with one part water in a spray bottle.
Spray the vinegar and water solution onto the faux leather and allow it to sit for a few minutes. Vinegar is a natural deodorizer and although it has a strong smell on its own, that smell disappears as the vinegar evaporates.
Wipe down the faux leather furniture with a damp cloth and smell the furniture carefully to see if the rubbery smell remains. If it does, repeat the vinegar spray until the furniture is deodorized.
