The lights in the studio are all gray. How to clean them?

Disconnect the power supply first, remove the lampshade and lamp tube respectively, wipe the dusty place with soft cotton cloth dipped in water or a little cleaning agent, and then wipe it with clean cotton cloth.

Let it dry in a safe place, and then reinstall it.

Pay attention to the neutral and light cleaning agent, otherwise it will damage the reflective paint on the lampshade.
