Clentaminator

The Clentaminator is a Hardmode tool which can be used to create or destroy biomes. It uses Solutions as ammunition, with each Solution spreading a different biome. It has a similar firing pattern to the Flamethrower, but has a much longer range, fires through blocks and works in water. The Clentaminator is generally the fastest means of spreading or removing Hallow, Corruption and Crimson. It can also rapidly convert Jungle to Glowing Mushroom biome and vice versa.

The Clentaminator as well as most Solutions can be purchased from the Steampunker for and, respectively.

Solutions
There are currently five different solutions. Four of them are sold by the Steampunker, who sells different solutions based on certain conditions, and one is sold by the Truffle, who always sells it. For more information, see Clentaminator.

Tips

 * Since boosts which reduce ammo usage also affect the consumption of Solution, it is recommended to have at least two ammo-conserving items or buffs before using the Clentaminator. The following items may be used: Chlorophyte Helmet and (Shroomite Breastplate alternatively) give a constant chance to not consume ammo; while Ammo Reservation Potion and the Ammo Box provide temporary (but long-lasting) ammo-conserving buffs. Combining all four of these results in a 61.6% chance to not consume ammunition (including Solution).
 * It is possible to convert an entire world by digging Hellevators about every 116 blocks (232 ft/70 meters on the Compass) and slowly descending each one, spraying both sides.
 * It could be a potentially effective tool to search for Life Fruit when using Dark Blue Solution, as it will break them out of place and convert the Jungle foliage to Glowing Mushroom foliage – illuminating and creating a contrast between the background and the Life Fruit. However, note that this will most likely also break Plantera's Bulbs, summoning Plantera.
 * Glowing Mushroom can be produced at will by using both Dark Blue Solution and Green Solution in conjunction with the Flower Boots, by first growing flowers on jungle grass then converting it to mushroom grass, which can then be harvested for Glowing Mushroom for as long as one desires and/or has solution.
 * The clentaminator could be used to illuminate your map, since its spray emits a small light source.

Trivia

 * "Clentaminator" is a noun constructed from a portmanteau of the words "to cleanse" and "to contaminate", these being its two major uses.
 * It is tied with the Diamond Ring and Tiki Totem as the fourth most expensive item players can buy (behind the Steampunk Wings, Parrot Cracker, and in ascending order).
 * When using the Clentaminator, an apparatus can be seen on the character's back. A similar effect also occurs when equipping the Heat Ray, Leaf Blower, and Elf Melter. The apparatus is, as with the items listed above, invisible when the player wears wings and is midair.
 * Standing on a corrupted block while using the Clentaminator upwards will purify the block.
 * With the introduction of the 1.4 update, it is now possible to get both Red and Purple Solution in a single world, with the Drunk World seed. However, only one can be bought at a time.
