I think if you sprinkle a little baking soda in there that could help with some of the more stubborn stains but vinegar alone works really well. I recently cleaned all the hard water stains off my sliding glass shower door with it.
I tried, but none of the 3 Lemmy apps I have (Sync, Connect, Jerboa) seem to be able to upload pictures. I would do it from my computer but I'm on vacation, going to Legoland for the first time in a couple hours. Maybe I can upload on Tuesday if I remember.
Still doesn't really seem all that big. Some EVs have 100 KWh batteries. A container ship with the battery capacity of 500 cars doesn't sound like much.
