I started out making manual repairs with Audacity and then using the Effect>Repair tool to fix them one at a time - effective, but very tedious.
Audacity does have a click removal effect but it’s not the “best in class” - following a steer from one of the other forum elves, Kozikowski, I then used Brian Davies’ excellent Click Repair to automate the process. See this sticky thread: https://forum.audacityteam.org/t/click-pop-removal-clickrepair-software/1933/1
It costs a little but will save you loads of time and it does an excellent job.
