The finish of the cabinet can be maintained by regular dusting and polishing using a soft microfibre cloth and furniture polish. The drive units should only be cleaned with a damp cloth if more than normal dusting is required. Never use solvents or aggressive cleaning agents on your Studio 89 loudspeakers.
When in doubt, test the cleaning product on an inconspicuous area of the cabinet and let it sit for several days before committing to its use on visible portions of the cabinet.
