Care, maintenance, and cleaning
When the CI6 amp becomes dirty, wipe it with a clean, dry, soft cloth. If necessary, first wipe
the surface with a slightly dampened soft cloth with mild soapy water, then with a fresh cloth
dampened with clean water. Wipe dry immediately with a dry cloth. NEVER use benzene,
thinner, alcohol, or any other volatile cleaning agent. Do not use abrasive cleaners, as they
will damage the finish of the metal parts. Avoid spraying insecticide, waxes, polishing agents,
or any aerosol product near the CI6.
