When I saw this on Pinterest, I took action by making Anderson go to the auto store and pick up an oil pan. I haaate going into automotive stores. It's just that I am not a fan of being treated like I know nothing even though I actually know nothing about cars. Anyways, Anderson picked one up for me. I cleaned it and cleaned it and cleaned it, probably no less than 10 times. It comes with this filmy coating on it that is best cleaned with a grease fighting cleaner like dish soap or Lysol Kitchen (that's what I used). fyi, I tried Windex and it just didn't work that great. After it was all cleaned, we hung it with 3M removable Velcro strips.
This has been perfect for all of Sawyer's magnet toys. I have considered painting it, but am not sure yet. Translation: I'm lazy and this does the job as is. Sawyer loves it and I love that my refrigerator is not a primary colored hot mess.
