OXO Good Grips Sweep & Swipe Laptop Cleaner, White, One Size

How do you clean the micofiber pad?

is the cloth replaceable?

Are you suppose to wet the orange part because mines is hard and leave even more smudges with a trail on my screen ?

Does the microfiber side clean laptop screens well by itself or do I need to spray screen cleaning fluid on the screen or microfiber?
