I need a plugin that cleans up my models and make the file size smaller
Look at CleanUp3 in the Extension Warehouse.
Most likely, though, you’ll need more than just a plugin. You’ll need to learn how to clean up your modelsmanually. There’s usually stuff that needs attention that requires your decision making. A plugin won’t make those decisions for you.

Update your profile! Update it regularly if it is changed. SketchUp for Schools does not allow to use Extension, only desktop versions do!
(Please check my profile or Dave’s profile as example how we put different version, computer, licence info into our profile.) This help us to help you.
Thank you! I will look into it.
