Angular 2: remove CSS from dynamically generated component on destruction

How to remove all CSS classes that were added to the DOM when destroying a dynamically created component.

Create component (which adds CSS component classes to the DOM):

const componentFactory = this.componentFactoryResolver.resolveComponentFactory(component)
const componentRef = componentFactory.create(this.injector)

      

        
        
        
      

    

Destroy component

componentRef.destory()
// I need the CSS Classes which were added to the DOM to be destroyed as well

      

        
        
        
      

    

I cannot manually remove them because I have no idea what CSS classes are; so I need to remove all CSS classes associated with creating this component.
