Thread: Actual Testing OMG - Alcohol and Razors

Alcohol (C3H8O) itself obviously won't cause rust. But if you are using a low concentration solution that has WATER in it, then you will run the risk of rusting. I guess Glen's experiment sheds a little light on how low you can safely go. I would assume that the rust spots from the splash occurred because the alcohol there quickly evaporated, leaving behind some water residue. But in the solution itself, there must not be enough free water to cause rusting.

I wonder how long you'd have to let it sit for enough alcohol to evaporate to cause rust under the liquid line.... And how low (in concentration) can you safely go. Those would actually be interesting tests.
