What is the right way to clean up $title before wp_insert_post?

Question

I am using a function to insert some post data and i am having problems with the title/title - slug. The title is random selected from an array, some title have ?, ! or . (dots)

I notice wp_insert_post doesn't clean up the title so in the title slug (permalink) i see the ?, ! or dots. How can i fix this? Any WP built-in function?

This is my function

function my_add_post($title, $content){
  // Create post object
  $title = str_replace('.','',$title);
  $title = str_replace('?','',$title);
  $my_post = array(
    'post_title'    => $title,
    'post_content'  => $content,
    'post_status'   => 'publish',
    'post_author'   => 1,
    'post_category' => array(1)
  );

  // Insert the post into the database
  wp_insert_post( $my_post );   
}
