I would one function to be included in my function.php theme.

i found this:

If you put this in your functions.php, it will delete all the HTML comments that are in your code.

function callback($buffer) {
    $buffer = preg_replace('/<!--(.|s)*?-->/', '', $buffer);
    return $buffer;
}
function buffer_start() {
    ob_start("callback");
}
function buffer_end() {
    ob_end_flush();
}
add_action('get_header', 'buffer_start');
add_action('wp_footer', 'buffer_end');
