Hi ahanford,
Select the object and press u then o key (do not move the mouse or pen). That should clean it up.
This is the Optimize function that you can find here
Main Menu> Mesh> Remove> Optimize (cogwheel: for more options)
If I had the file here, I could advise about the Tolerance settings. If they are too large, you might destroy your object. So save first.
Cheers, stay safe, stay healthy.
