job effectively. Clean the outside of the environmental chamber with soap and water or
with any non-abrasive commercial spray cleaner. Clean the inside of the chamber with
alcohol and/or soap and water. Disinfect the interior panels with a general use laboratory
disinfectant, diluted according to the manufacturer's instructions. Rinse the surface
thoroughly after each cleaning and wipe the surfaces dry. Always rub in the direction of
the finish polish lines.
