Did you ever have something so burnt-on that even boiling water with dish soap wouldn’t loosen it? The picture below is of burnt oil and onion so thick and caramelized that nothing would budge it. My son had burned onions and mushrooms in my pan. Whoops!
I thought that I was going to have to throw my wok away but I instead I grabbed my Thieves household cleaner that I used to make a soft scrub. It was working so well after a few seconds that I took a pic when I started and then again 20 seconds later.
Wow! Can you believe the difference?!
(BEFORE) (AFTER YOUNG LIVING THIEVES- WOW!)
