How to use Vaseline and absolute ethanol to repair sticky equipment caused by hydrolysis

I'm going to give a lecture at Machi Asobi for the first time in a while , so I took out the Logitech laser pointer ' R800 Laser Presentation Remote Control ' that I was using for the presentation from the equipment room of the GIGAZINE editorial department, and it had undergone so-called hydrolysis and became sticky and sticky...
