Crafting recipes that have to do with the soap for the washing machine and dishwasher duplicate buckets. Crafting it requires a bucket of water, but leaves behind the bucket in the crafting grid while in the output you get a bucket of soap, which when used, surprise, leaves behind the bucket. There is a higher tier of soap crafted from the first soap as well. You can turn one bucket into 3 by crafting up to that soap.
