The frames should be washed with an automotive type soap and thoroughly rinsed. It is recommended that at least twice a year, you wax your frames with an automotive type wash/wax, preferably one with the wash and wax combined. Please follow the directions from the wax manufacturer. The frames should be rinsed again thoroughly to remove any residue. It is strongly recommended that before waxing the frames, the frames should be inspected for chips in the finish, which may occur under normal usage. Any chips or scratches can be easily repaired by following the instructions on the back of a can of touch-up paint. Simple maintenance will insure a lifetime of problem-free usage.
