Maintenance
Cleaning the exterior
* For normal cleaning, use a soft dry cloth.
For stubborn dirt, moisten a cloth in diluted detergent, wring it out firmly, and wipe the dirt off.
Then polish with a dry cloth. Never use solvents such as alcohol, thinner or benzene, since these will
damage the printing and finish of the exterior.
