Sometimes when remotes stop working, the problem could be from old batteries left in the remote that leaked battery acid and caused corrosion to appear. This guide will help you take apart and clean the corroded areas in a Nintendo Wii remote. As this deals with batteries that leaked, safety precautions should be in place, like gloves and proper disposal of the batteries.
It is important to note that while this guide helps clean corrosion, batteries are not the only cause of faulty remotes, since water damage can also cause corrosion on the motherboard.

Would 99% Isopropyl Alcohol also be okay to use as cleaner?
Of course, I use this for cleaning every type of motherboard, the difference between 99% and 70% is that the solution contains less water, so the liquid evaporate in less time :)
