I had been using an old 15ml juice bottle to clean my attys. I'd let them soak and then occasionally shake the bottle to agitate the atty for a little extra cleaning. Lately, I had an atty where there wasn't sufficent silcone used in the construction so the coil assembly wasn't secured inside the tube. As a result the coil assembly broke loose from the brass base during the agitation and came out. It was easily fixed with a little solder and a drop of Super Glue, but I have since eliminated the agitation during the cleaning process. I thought I would pass along my experience in case someone else is doing the same type of cleaning.
