Getting Rid Of Corruption/Crimson Biomes Corruption/crimson biomes are dangerous biomes that spread though other biomes. There are a couple ways to prevent or slow the corrupion/crimson from spreading. First if you in a non hardcore world you could try building a wall out a material that is not affected by the corruption/crimson. Stone, dirt and sand will not work so try wood. Purifaction powder works good and is bought from the dyrad, but however does not actually remove the biome. Once your in hardcore and have beaten one mechanical boss the steampunker should move in. The steampunker will sell a item called a clentaminator. And depended on the biome your in solutions can be sold to purify or make a biome in a certain area. This covers a much larger area than the purifaction powder and once you have covered the land area the biome should eventually turn into a normal forest (Hallow or whatever solution you used).
