VSX-49TX :
Maintenance of External Surfaces
Use a polishing cloth or dry cloth to wipe off
dust and dirt.
When the surfaces are dirty, wipe with a soft
cloth dipped in some neutral cleanser diluted
five or six times with water, and wrung out
well, and then wipe again with a dry cloth. Do
not use furniture wax or cleaners.
Never use thinners, benzine, insecticide
sprays or other chemicals on or near this unit,
since these will corrode the surfaces.
