Corrupted Snow Biome!

[sometimes i do drugs]

I finally got the corruption under control mostly but it corrupted a snow biome to the left of my spawn. I was so tired of digging helevators that I just tried using tedit but it doesn't remove the purple snow blocks, especially underground. I don't mind if the snow biome gets corrupted, but will it spread to my grass biome? My mine is very near to the underground snow corrupted biome, and I'm scared it'll spread to the stone and dirt blocks. Should I just dig another few hellevators and blast it with green solution?

Maybe I should just dig a hellevator from the bottom of the dungeon and move to the beach -_-
