Do -Infinite volume audio clips take up size/space?
This is sort of an odd question. I’ve been cleaning up all my audio with soundsoap, a shot at a time, exporting the clip’s worth of audio, cleaning it up, re-importing it, and replacing the original audio with the cleaned up AIFF. However, I keep the original clip audio in place, turned down to -infinite dB, for a guide track, in case I ever come up with issues and need to use the original audio track. If I export, say, these volume clips turned all the way down, or a video clip that overlaps or sits on top of another, but the one on top is at 100% (not semi-transparent and showing any part of the other clip), does it add to the file size or render time? Just wondering if I should delete all those turned down tracks before I do the export or if they do not harm staying there.

Turning down the volume doesn’t affect the size of the original media. If you are asking that an OMF axport will include the media, the answer is yes if it is on another track. If you replaced the audio by overwriting the original, then it isn’t in the timeline anymore so won’t be in an OMF export.

Allow me to rephrase that.
I have audio connected to video.
I exported that audio to other software to clean it up.
I re-imported it into Final Cut cleaned up and lined it up. So now, there are two copies of the same audio, one the original attached the the video, one the cleaned up version.
I turn the original all the way down to -infinite dB. It’s there as a guide track only, in case I later learn something isn’t clean enough or otherwise need the original audio.
Is it going to take up space in the export, despite it being turned down completely, because it’s still there?

No need to rephrase as I understood. If the audio clips are on another track they will be exported via an OMF and take up space. You haven’t defined what you mean by export so I am assuming OMF as that is the common way to export audio for sound post.

AIFF. I believe I said that.

Are you asking if your ‘muted’ clips will affect the total filesize of your final export of the programme? If so then the answer is no. They may affect render time but the difference would be minimal. Why not just disable the audio clips or just mute the tracks where your original audio is.
Regarding export all your audio tracks are (normally) mixed down when exporting. So in theory it doesn’t matter if you have 49 loud clips stacked on top of each other or 49 totally silent clips. The number of samples in you master file will be constant. (I’m obviously disregarding any type of audio compression.)
But why not make a test for yourself. Export once, remove the silent clips and export again, compare the filesizes… That way you will now for sure.

If a tree falls in the woods and no one is there to hear it, did it make a sound?
Sorry, couldn’t help myself.
If you export a stereo aiff, they aren’t going to make a bit of difference to file size. If you are exporting a multitrack audio file, it will.
