Going to assume your collection exists in this class:

public class MyArticlesBrowserViewModel {
  public ObservableCollection<ArticleDetailData> LastThreeArticles { get; } = new ObservableCollection<ArticleDetailData>();
}

Then create a new instance of this class which contains the reference to the collection:

public static void MyStaticMethod() {
  var myArticlesBrowserViewModel = new MyArticlesBrowserViewModel();
  // This is your instance
  var myCollection = myArticlesBrowserViewModel.LastThreeArticles;
}

public static void Clean()
{
  var myArticlesBrowserViewModel= new MyArticlesBrowserViewModel(); 
  myArticlesBrowserViewModel.LastThreeArticles.Clear();
}
