I found a more environmentally clean option.

Homemade water based cleaner recipe that worked well in a sprayer bottle.

8 oz. water
1 Tbsp Vinegar
1 Tbsp Baking Soda
1 Tsp Dish Soap

Leave out the vinegar and baking side and I bet it will work just as well,
just not put on as much of a show.

The vinegar and baking soda reaction will produce quite a bit of foam,
where the collapsing bubbles might simulate the cavitation from an
ultrasonic cleaner. I've never tried it, but it might improve the
detergent action of the soap without the need for an ultrasonic
cleaner.

1) plain old white vinegar
2) salt
3) baking soda
4) lemonshine
5) citric acid

Notice the vinegar and baking soda in the recipe.

I understand the concept, but I can’t imagine the collapsing bubbles
imparting any substantial amount of physical scrubbing action. Maybe the
expanding bubbles might force the soap solution deeper into parts, but at
that dilution ratio, and considering that you’re supposed to mix it
together in a spray bottle BEFORE using it, I have low hopes. If I had to
come up with a homemade EZ-Clean solution, I would use dish soap and
boiling water.
