Brewing Acid Potions using Sulfur

One of the main uses of sulfur IRL is Sulfuric Acid, which is used to clean metals such as copper. We should be allowed to make sulfuric acid by mixing a (splash) water bottle with sulfur in a Brewing Stand. This would give us a (Splash) Acid Potion, which we can then splash onto copper armour/blocks, or add to a Cauldron and clean our tools with it. Furthermore, Copper Sulfate is the same colour as the Blue Dye ingame, so it would be cool if we could make Blue Dye whenever we de-oxidise our copper.
