Check the Admin Item Spawn IDs thread

What is the tagname, so i can change the crafting ingredients?

Dont drop it tho ;)

Thanks @Dragnier Draconai it's here if anyone needs it and the size is less than 1mb.

Great for nearly vanilla. Only useful in modded should you decide to revert armor/saddles to their original color instead of just recoloring it. Walls and building parts usually revert color when picked up and re-placed. Nice proof of concept for a vanilla addition though!

@Archemedes is it re usable forever, you make one and you can use it forever.
@Fredfinger @tacticalRhino soap is used to remove dye from armor, saddles, or even walls and foundations. It can be used to remove dye from anything.

why soap? what does it do?

What is the soap used for?

How reusable is reusable? Is it a permenant item, an item with more uses per soap?

Yep, soap is very clean, and stacks well too when you have square blocks of it.
