* you can use soap, just not one with a perfume, example straight A or B-brite
* if the bucket is clean enough to not carry an infection to the next batch it is clean enough (I use tap water/ run straight A through tubing that I can’t actually scrub). The dilution factor is enough on your fermentation bucket the flavor would not be noticed
