PSA. DONT DO THIS. Whatever you do, do not dump tomato sauce on bronze statues that celebrate racial oppression. If you were to do that, the chlorides in the tomato sauce would react with the copper in the bronze and the oxygen in the air and cause irreversible "bronze disease" that never stops spreading and we actually once thought was caused by some sort of bacteria because it's such a difficult thing to stop that it spreads like a disease. For my chemist friends this is what the reaction would look like: +H2O → 2HCl + Cu2O 2HCl + 2Cu → 2CuCl + H2 That would cause the bronze to discolour, chip, flake and decay, like the examples below. This would be better for the environment and more difficult to fix than spraying paint over things to have it be power washed into the soil. Again, and I cannot stress this enough. DONT POUR TOMATO SAUCE ON STATUES OF RACISTS ITS ILLEGAL
