I hate any type of dirty dishes or soaping equipment sitting around. So I do as Erelene and clean out all I can get out with a scraper, then I take old rags from a batch I keep just for wiping out my bucket and measuring cups I use for soap. I then toss the rags in a bucket for a few days, until they are now soapy not oily.
Being so paranoid about dirty dishes
I even wash everything in between batches, which could up to seven batches on a good day. But not many of those days anymore
. I soap in hdpe buckets so I fill them with hot water, Dawn and some additional degreaser, which is where I wash all the utensils, by then the bucket is clean and the water is tossed over my bank, and over the roses when aphids are bad. It keeps the whiteflies and aphids at bay, so a win win. I have to much plumbing problems to put the water down the drain, even when all is wiped clean. Sometimes I tell myself I will not take as long making my batches and not wash in between , but nope, that does not happen.
When and if my buckets feel a bit oily even after a good washing I spray them with alcohol.
Forgot to add I never never put my soaping equipment in my dishwasher. It just does not take much to leave a film in the dishwasher. Soap itself can also clog drains.
