Xbox Series S/X 1% Corrupt and Crimson Pain in a drunk world.

[Harvenger]

I have been trying everything to completely purify my large world (which is already a pain in of itself lol), and cannot find the last 1% of the crimson and corruption. I was able to completely clear out the hallow, but the others have not disappeared yet. I was wanting to clear them out before making artificial islands to house them. I have dug through the entirety of the world in close holes (enough where I can see 3 at a time when zoomed all the way out), used the clentaminator, and though I had gotten everything, but she still claimed I was 1% left. I then searched the bottom of hell and all of the sky islands and sprayed them down, but no luck. I tried using the biome finder potion (87 of them I think) to see if anything popped up, but no luck. I sprayed all edges as well, but that didn't work as well. I am completely out of ideas, anyone have any tips? I want to use a map viewer, but I know Xbox can't do that.
