Milk can remove all potion effects active on the player. You will need a bucket to get the milk from cows. To make a Milk Bucket, you’d need Iron Ore, Iron ingot from Iron Ore Using Furnace and Iron Bucket. Please follow the following steps to make a Milk Bucket.
Find at least three iron ores. Take your stone pickaxe and find some iron ore blocks. You will find some under the ground.
Iron ingot using furnace
We need to use the furnace to make iron ingots. Make your way to the furnace and add coal and iron ore blocks in it. Add three iron ores to get three iron ingots. Add these iron ingots into your “ready to use” inventory.
Now you will be able to craft an iron bucket because you have got all the required items. Move to the crafting table and add ingots in 3*3 crafting grid in the same way as shown in the image below. You will need exactly 3 iron ingots to craft an iron bucket. Add an iron ingot in the middle cell of the first column, last cell of the second column and middle cell of the third column. You will get an iron bucket in the right side box of the crafting table. Add this bucket in your “ready to use” stock.
Now you have to find a cow and then right click on the cow while holding the bucket, you will get milk in your bucket. Drinking milk can remove all potion effects active on the player.
