MacBook Trackpad works but doesn't click. (Liquid Damage).

I recently spilt coffee on my MacBook trackpad, quickly tried to wipe it off but some of it seemed to have seeped through. Everything works properly, I haven't had any issue with the MacBook except for the click. The trackpad doesn't seem to click anymore.

I took it to apple and they said I have to replace the whole logic board and the trackpad, and that it would cost me about $1299 which doesn't make sense. After a while the trackpad click started to work again, but only slightly, I can feel faint clicks every time I press down on it.

Should I get a replacement trackpad or should I just try and clean it up once and see if that helps, there are coffee stains inside the MacBook. If I can clean it, How would I do it?

Are there kits from IFIXIT to handle such cases?
