“Attitude is a choice. Happiness is a choice. Optimism is a choice. Kindness is a choice. Giving is a choice. Respect is a choice. Whatever choice you make makes you. Choose wisely.”
Roy T. Bennett, The Light in the Heart
Ultrasonic cleaner has a depth of 60mm and the neck of the average cylinder is 80-90mm which means the
cylinder will not ground on the edge of the bath. As the threads are no more than 30mm deep the bath
only needs to be half-full. The plastic tray is used purely as a buffer to stop metal to metal contact and give
a bit of grip.
Cylinder is lifted upside down placed carefully in the bath and manually supported upright for about 60 seconds.
Testing (service) is every 15 months and for this taking a valve out way OTT. I've got about 30 cylinders here
of all sizes (eight are 15's BTW) and do the lot once every 6 months in-between test intervals.
Been doing it this way for well over a decade now with good results and weirdly have not ever had a problem
