Best way to "Cleanse" a world of Corruption and Hallowed

[MOXzy]

I'm aware of the Clentaminator and I do use its just both biomes have become really out of control, Open to any ideas, strats, or even help in doing so.

How " out of control" is it, exactly?

I just throw down lots of Hallow seeds when I hit hard mode, esp at the borders of corruption/crimson. This makes hallow take over, but I prefer it over the 'evil' biomes. Other than that, all I can think is you can always make a sky bridge out of dirt where it's too high up to spread.

You can also stop the spread around your base with walls but that feels like more work than anything else.

The best way to clense an entire world is to dig tunnels strait down spaced out in incraments of 100, then ropeing all the way down each tunnel, spraying one sie on the way down and the other on the way up. (There are accessories that can tell you the east and west measurements.) It'd be best to try and do all the cleansing in one go after you dig the tunnels, or else your world is just going to recorrupt/recrimsom/rehallow.

Dig 3 wide tunnels straight to hell about 25-40 blocks from one another and fall down each of them spraying the clentaminator as you go. Easiest way I ever found. Surprisingly it doesn't even take that long.

What I usually do to contain the bad spreads is dig a two or three block wide hole at the edge of the spread and place some pearlstone down there instead, so that can spread and block off the crimson/corruption. but if you're looking to get rid of both, that might take some extreme excavation without using the clentaminator. I'd be willing to help if you're going for the excavation methods.

you need 4 wide tunnels. corruption/crimson/hallow can spread otherwise

[Gaydalf]

you can use 4 wide ores or clay block too, as they dont get taken over

This is all great to know. I'm assuming if I rid a given biodome completely then it'll NEVER regrow. Is this actually true?

Unfortunately, the best approach to preventing corruption and hallow from taking over is usually a proactive one. I at the very least dig boundaries around the corruption/crimson in the world before I ever go to hardmode, so I at least have a bit of a head start.

Ideally you would have all the biomes you cared about isolated so that any contamination that occured when entering hardmode could be easily taken care of with the clentaminator and then you wouldn't have to worry about it becoming contaminated again. Luckily, you can always save a world, even if you didn't quite prepare enough before hardmode. Just start digging borders around biomes at least 4 blocks wide and then clentaminate them. Assuming the borders are correct, once you purify all blocks within each area you zone off, it should be safe in the future, allowing you to focus on other contaminated areas.

This is probably obvious, but I would suggest leaving some corruption and hallow in a world so long as you can keep it well contained. Just for the biome specific items they have to offer. Bear in mind though, every time you break a demon altar or crimson altar there is a chance that corrupted/crimson blocks will spawn at a random location in your world, so that can contaminate a world you thought was secured.

It's not true, you can reseed it if you save some of the hallow/corruption/crimson blocks. You can also create artificial jungle, mushroom, snow, and desert biomes as well. The only thing I know of that can be destroyed completely is the Dungeon, but that would require you to dig it out entirely, backdrop walls and all. The ocean could be drained entirely too, if you really cared to do so.

If the world is completely cleaned, is it possible for corruption to randomly spawn and spread. Assuming no altars are broken

Date....
Also i'm pretty sure beating WoF will spawn more.
