My LG pad F 8.0 has glue problems.

So I am not sure what to do because my mom won’t take me to a store to get it fixed, and I guess we’re gonna fix it at home. But I need help. The glue inside the screen is like spreading into the screen and making weird circles and smudges and shapes. I just need help on knowing how to fix it without having to spend a lot of money or do too much work. I know I have to work to fix it but I just need the least complicated way to fix it.
