Potion of Milk/Cleansing

When adding a milk bucket a brewing stand holding awkward potions, you will get a potion of cleansing. What makes this different from regular milk is that when drunk, the player will receive the cleansing effect for about 30-40 seconds. For the time cleansing is applied, the player can not have any other effects applied. This makes for a sort of neutral potion that can be used for good and bad. Potions of cleansing can also have redstone added to them to increase the cleansing time. You can also use gunpowder and dragon's breath to make splash potions and lingering potions of cleansing. Some examples of good uses are using the potion to fight witches, husks, cave spiders, withers, wither skeletons, etc. Some bad uses are splashing your friend while they are in a lava lake with fire resistance, underwater with water breathing, or trying to heal with golden apples.
