Many treat click disease by replacing buttons or the mouse itself))). I found a more cost effective way. The buttons are disassembled with a small scalpel. The buttons are assembled on latches, easy to disassemble and assemble. The contacts are covered with silver, and it tends to oxidize. They are wiped with alcohol, which easily removes black plaque. And you can forget about this problem for several years. A few years later, another preventive maintenance is carried out, etc.
