I spilled oil on my Surface Pro 6 tablet and it seeped inside the left speaker causing some display damage (streaks and blotches). Some also seeped inside the top vents and got trapped above the camera and under the display casing. The tablet is still functional as well as the blotched areas. What can I do?
You will need to get the screen replaced to fix that. Personally I would leave it because the price of a screen is around $200 or more if I remember correctly.
