Chosen Solution
I accidentally drop 0.5/ 4 amount of energy drink over the right side of my keyboard. It’s not much but it’s cover almost the right side of the keyboard including the right speaker on my 15" First, I power off my macbook pro. Then clean the keyboard and speaker part with cotton cloth and. Then after everything on keyboard was clean, I get the toothbrush and used it to clean edge of the keys at keyboards and take out the remain water. And then turn the macbook upside down with the help of gravity to pull the water. Nothing goes out. And then I start backup my data for 1 and half hr without charging and instead connect external USB on the left side where no liquid damage. Then I turned it off completely, flip it down and place the keyboard on the table where cotton cloth or dry bath tower underneath. And turn on the fan by giving air to flow right through to the macbook pro air circulation door which exist at the button top side while turning it upside down. I am going to set this up to 2 days, see if this work after 2 days when charging. Any suggestion? I just bought that macbook 2 weeks ago. And I don’t want to lose it.
Since you’ve probably already voided the warranty I would recommend taking the MacBook apart and soaking the parts (especially logic board) in isopropyl alcohol and remove corrosion.
