Greetings, I have disassembled my MacBook Pro and completly removed the keyboard and keys. The plastic keyboard sheet the keys attach to is very dirty - covered in crud. I am cleaning it because the TYUIO keys work intermitently. It happened before, and I fixed it by removing a hair from under the E key. I am posting to ask what is best to use to clean the keyboad sheet with. Water? Soap and water? Alcohol? Thanks

Dip a cloth or towelette into isopropyl alcohol, and wipe it along the inner surfaces. make sure don’t use excessive alcohol it may damage the keyboard
