Php help with excerpt

Hello,

Can someone provide me with a simple php code that will allow all html tags in my excerpt. I tried a simple “The_content” tag but it’s screwing up my site. What’s a basic code I can put in my theme editor that will allow HTML in my excerpt?

I’m using the current code:
<p><?php echo dp_clean($post->post_excerpt, 1000000); ?></p>

It will not allow HTML in my excerpts. Please help. Thanks
