n
When solvents such as benzene or thinner, or acid, alkaline or abrasive detergent, or chemical cleaning
cloths are used on the dirty cabinet, the surface finish may be damaged. Take care with respect to the
following:
. Clean the cabinet with a 50 to 70 v/v% concentration of isopropyl alcohol or a 76.9 to 81.4 v/v% con-
centration of ethanol.
. Stubborn stains may be removed with a soft cloth such as a cleaning cloth lightly dampened with mild
detergent solution and then clean using the above chemical solution.
. Do not use unnecessary force to rub the cabinet with a stained cloth. The cabinet may be scratched.
. Do not keep the cabinet in contact with a rubber or vinyl resin product for a long period of time.
The surface finish may deteriorate or the coating may come off.
