I use a static microfiber duster. It basically grabs the dust off them.
Use a Wet wipe and go with the grain of the fabric and don't press hard. Wet evenly over the whole shade.
Hi Lin: Depending on what it's made out of, you can vacuum, using that little brush attachment and then, if there are stains, use a sponge dipped in a little warm soapy water and rub lightly.
I vacuum mine with the brush attachment and it does great
I use the brush attachment on the vacuum cleaner on cloth shades. For the glass lamp shades I use a damp cloth.
Wipe with a damp cloth or use a lint roller

Hello. It may depend on your specific type of lampshade.
Sometimes they can be more fragile than you might expect.
Thin fabric shades can be torn using your vacuum attachment, at least it has once for me.
The vacuum and hairy attachment or soft lambs wool-swiffer sweeper might be used in the sturdy type of lampshade otherwise I would consider using something like a blow dryer to blow the dust off and then vacuum or dust the surface below away.
I'd use a handheld steamer.

Brush vacuum attachment should work or in a pinch I've used a fine household sponge.
