When transporting your cordless lamp, always handle the lampshade by its base to avoid dents, marks, creases, or tears.
For regular cleaning, dust the lampshade with a microfibre cloth or lint roller. If the lampshade is very dusty, use a hairdryer on a cool setting to remove excess dust.
For heavily stained fabric lampshades, first remove the shade from the lamp base. Then, gently hand wash it using a microfibre cloth and a mild detergent diluted in cool water.
