Lye didn’t dissolve completely

I've had that happen to me a few times. What seems to help is to run your lye pitcher through the dishwasher. Years ago, I would pour my lye water into the oils, fill the lye pitcher with water and stick my soapy stick blender in there. Sometimes there would be a film left behind and I think that really interfered with the lye dissolving. So I never put my soapy stick blender in the lye pitcher, and I run it through the dishwasher after each batch. I store it upside down so it doesn't get dust in it.

I have dedicated lye jugs now too. I rinse them in water, not detergent and dry them upside down.
