How to Cleanup Adobe Illustrator File

Adobe Illustrator have one nice command to cleanup document from stray anchor points (single anchor point without path), empty text objects and unpainted objects (objects without any fill or stroke applied). Note: Illustrator treats single click with Paintbrush Tool as stray anchor point.

To cleanup your document go to Object > Path > Clean Up… and select in Clean Up dialog what you want to clean in Delete section, then click OK button.

Go to Object > Path > Clean Up to open Clean Up dialog in Adobe Illustrator
