The benefit of cleaning equipment out regularly is that your stuff lasts longer but also because you remove or rather reduce the chance of spoilage if something is left behind. I use a cleaning product like Grindz, but also, and here's my ultra top hidden secret I've never mentioned before.... Cheap vodka! Yes siree, it works. I picked the tip up from a barista in my youth. She'd told me any plain cheap vodka would work. It cleans oils and sterilizes equipment. It also isn't a detergent so it won't alter the flavor of your beans. I typically use a teaspoons worth on my hands mixed with hot water and then they get scrubbed down with a stiff brush and then a sponge.
This post took too much effort to compose. I think it's time to retire to bed.
Wonderful suggestion.
And now that brings me to the question as to whether denatured alcohol be as good?
