How would you clean up a project thats a year old and got inputs with instructions/triggers still in it that have since become unused


my example would be our social zone, an input that plays music with a looping background and and Instagram pics looping and then when the song finishes it cuts away automatically.
It has over 30 triggers related and it's right in the middle of the project.
And then I've got a desktop capture input right in the middle from when I did a tutorial.
I'm not sure what's best, going back through or doing a project rebuild once a year like a car service

if its not a topic you want to discuss please don't just send links, thank you
