Hey guys how do you handle cleaning up styles? It seems I'll be deleting a bunch of the Client-first style guide styles if I just go in and delete...
hmm you should be able to use the clean up tool just fine - I use it all the time - many many times throughout a project. If you are seeing CF classes it means you dont have them stored on the style guide page anymore. I would keep the style guide page intact as it was when you cloned it to ensure that no classes disappear.
If you want to "keep" a class that you create but maybe its not being used - just store it on the style guide page and when you go to clean up unused styles, it will not be included.
