For development, It is good to keep comments in your code. Don't remove them. You cannot let your comments locally and commit non-commented files, because when checking out your repository, it'll have no comments at all.
Through comments, other developers are able to figure out what's going on much faster and be more precise as well. They can find bugs and improve your code. So, comments are cool. I mean, good comments. I know code must speaks by itself, but comments are important as well.
If you intend to save storage, please, don't do that for development process. What you can do is deploy your code withou any comment, and, if possible, compressed.
We are being programming language agnosic, but I am pretty sure every language has some way to strip out comments and optimize it for deploy.
