I've often looked at doing it, but always chicken out when I start to

Well, yes; but there is a risk you will make things worse or not be able
to reassemble them successfully.

Most binoculars have several lenses and in some cases they are cemented
together so this could cause you some issues, best to google & utube for
more info.
