Hi Joe,
You could try this to strip out all HTML tags. Might be good to do this for RSS:
<?php $steps = get_field(‘step’); ?>
<?php if($steps) { ?>
<p>Directions: </p>
<div>
<?php foreach($steps as $step) { ?>
<p><?php echo strip_tags($step[‘add_step’]); ?></p>
<?php } ?>
</div>
<?php } ?>
Here’s the documentation: http://php.net/manual/en/function.strip-tags.php
