The original post shows it being done to the back of cookie sheets. I don't care about the back because that's not the side that you put cookies on! So I decided to try this out on the front side, the side you would put cookies on.
Step 1 - I found an old cookie sheet
Step 3 - I then poured hydrogen peroxide on top of baking soda
Step 4 - Finally I poured baking soda on top of hydrogen peroxide
Step 5 - Then.. the waiting game.
Now I wasn't sure how long to wait (the original post said 2 hours) so I broke up the pan into fourths so you can see what happens after 1, 2, 3, and 4 hours. Note that I did not use a sponge or scrub it, as the original post said "Minimal rubbing with my fingers was required."
Hour 1: I just wiped off the baking soda with a soapy paper towel... and found no difference whatsoever.
Hour 2: Still no difference
Hour 3: Sigh... still nothing...
Hour 4: It looks exactly. the. same.
So another case has been solved of "What's on Pinterest Should Stay on Pinterest and Not Be Tried At Home!"
TOTAL COSTS: About $3.50
$1.49 for baking soda from Vons
$1.99 for 32 fl. oz of hydrogen peroxide from Vons
TOTAL AMOUNT OF TIME: 2-4 hours
Depending on how much time you want to waste
EASY-PEASY SCALE (1 super easy - 5 very difficult): 1 out of 5
It's so easy you'll wonder why you did it at all after reading this post!
