| hi /diy/, first time posting here | |
| how do I corrode aluminium? It's not urgent but it must be significant corrosion, not only surface | |
| I tried searching google but every link that I get from googling is how to prevent corrosion lol, closest thing I found was using HCl but I doubt that it will be enough to corrode | |
| thanks | |

| Buy a new car and move to the rust belt. | |

| Wait longer. | |

| If aluminium is exposed to very strong acid or alkaline environments outside the pH range 4 to 9, violent corrosion will occur in the form of metal pitting. Bases break down the aluminium faster than acids - for example concentrated caustic soda reacts so violently with aluminium that it can start to boil. | |

| Apply liquefied gallium to a roughed up aluminum surface, it will infiltrate the crystal structure and make the aluminum ultra brittle. | |
| Also, it will be super obvious if you did this, and gallium will stain everything it touches. | |

| You're not corroding aluminum, because the surface is already corroded. Aluminum forms a layer of aluminum oxide, i.e. alumina, on contact with air. This "protective" layer is why welding aluminum is such a bitch. | |
| Your options for rapid weathering are basically galvanic. Dunk it in a salt brine and mechanically scrape it as best you can to tear away some of that oxide layer. Attach a DC electrical lead to it and throw in a chunk of copper to the other. The aluminum will have a very bad time. | |

| I once put some stained metal parts in bleach in order to remove the stain... 1 week after I removed them they turned into balls of pure rust. worth a try | |
