Spilling Sulfuric Acid on Your Shoes is Really Not Advised
We do not recommend that you go pouring acid on your shoes, if you do, please take your feet out first. Sulfuric acid is a nasty acid with a pH of .3 when the Normality is 1, you definitely don't want to get this stuff on your skin. When poured into a shoe, it immediately dissolves the ink and starts eating away at all of the material. You can check out more of the reaction in the video above.
