OOP | Data escaping related question

Hi everyone,

I am developing a login system in OOP php and I was curious what the outcome of one particular line would be.

  public function clean($data)
  {
    if(!empty($data))
    {
      $data = trim(strip_tags(stripslashes(mysql_real_escape_string($data))));
      return $data;
    }
  }

        $username = $loginSystem->clean($_POST['username_']);
        $password = $loginSystem->clean($_POST['password_']);

If I use this function to literally 'clean' the input data, like for an username or password and I am using a special character password like 'FFe89!Gzt@r)6z'. Will my code clean the characters in my password?

Or a rather different question, how will this function behave for crud operations
