Wow the guy in the video used a ton of that stuff. I have electric contact cleaner and use just 2-3 squirts. It works but not for very long. Is there a danger to spray until it drips out of the joycon?
I did the same...and it worked...but not for very long, like you say. I was wondering the same and whether I should have just drenched the thing the same way.
Also wondering how many times that guy has smashed his fingers and thumb...ouch.
