So ive found the cip cleans the top of the top 3 elements but does not clean where the sprayball doesnt directly strike including the lowest element which needs to be submerged in order to allow the cip pump to not pull air in from the bottom ive tried this with our pump both at full blast and throttled down (48gpm pump generated enough pressure where the liquid sprays through the seals in the top of my sungood kettle.
We have not tried acid yet just pbw with 170degee water. the rest of the kettle is cleaned perfectly.

we have to pull the elements and wipe them down but the tan buildup comes right off.
