For awhile I wasn't using distilled water, used it the other day, one cycle of 30 minutes, done. Dry them off and tumbled. As far as a homemade brew..... if you can't find a cheaper version of Hornady sonic cleaner, such as Frankford arsenal cleaner, then it's hard to replicate either. What's cheaper in the long run is SS pins with Dawn DWL and a decent tumbler, your choice depending on volume. I rigged up a 5 gallon bucket on a base out of two by fours and caster wheels, bike tire contact cemented to the bucket on the drive wheel, found some aluminum angle and bolted to the inside of the bucket. And away it went.
