Care and Cleaning Tips
Caution!
Improper handling of the speaker may cause damage.

Housing
We recommend using a standard glass cleaner sprayed onto a cotton cloth. This allows most fingerprints and dirt to be removed easily. Alternatively, you can use window active foam. We advise against using microfiber cloths as they may cause micro-scratches on the surface.
Membranes and Speaker Drivers
To remove dust from a speaker driver, use a lint-free cotton cloth and gently wipe the membrane with very light pressure. All Nubert speakers' tweeters are protected by a grille, which can also be wiped lightly with minimal pressure. If the dust cannot be completely removed, a makeup brush from the drugstore can be used.
