hi all, I have used a magnetic flap pouch to carry my MacBook Pro 14” and it seems to have caused a white stain on the aluminum body where the magnet position is.
Anyone have any idea how to remove this stain?
 
It may not be a stain at all, it may be from a part of the case rubbing against the MacBook.

When running your finger over the "stained" area, do it feel any different than other areas of the top case?
 
If it's caused by abrasion, it's permanent. Next time put it in the pouch with the flap to the bottom of the case.
Or get a pouch designed to protect the device, not damage it.

The stain is smooth like the rest of the surface. Using alcohol wipes doesn’t seems to remove. It looks like u put a magnet on the fridge and after sometime u remove it, there is a stain, like outside the magnet area has aged more.

It could be from abrasion because the inside of the carrying case is probably smooth and could have been rubbing against the MacBook like very fine sandpaper. I often use fine grain sand paper to get a smooth finish on wood and plaster.
 
"white stain?"
Not really a stain, just the result of the inside of your bag rubbing on that area.
The magnet makes that flap on the bag less flexible, so friction has marred that area a bit.
You could try a Magic Eraser™ -- might help

Get a different carrying case.
That one has problems (you can see what they are).
