Using this Goby Labs surface cleaner is easy. First, shake the bottle well. Then, spray a small amount onto a soft cloth. Gently wipe the front panels, polished, fine wood, or piano black surfaces. Don't spray directly on the surface to avoid any possible damage. As for maintenance, keep the cleaner in a cool and dry place. Avoid exposing it to extreme temperatures. If you spill it, clean it up right away. And always test it on a small, hidden area first to make sure it works well with your specific surface.
