Hi all, here's another cleaning solution for your consideration. If you have a 3d printer, here's a cleaning wand
https://www.thingiverse.com/thing:6575160 Before making this I was using a 1 liter wash bottle but didn't feel like it was thorough enough.
The "hose_adapter_od" parameter in Fusion 360 lets you control how large the end of the wand is to match your facet and for me, I found that a 22mm (7/8 inch) inner diameter silicone hose worked well. To make the hose adapter on the wand tight, I made its outer diameter slightly larger, 23mm.

My 3d printer is really small so I separated the wand into 2 bodies that are glued together with epoxy. I printed the two parts in PLA and oriented them horizontally for the best strength. The glue joint adds a lot of strength as well and might be a good idea even for larger printers.

A silicone hose, hose clamp, and zip tie complete the project. All the edges are rounded over in the model but I also use some sandpaper to make sure there are no rough edges.

To insert the wand I cover it with foamed soap and pre-twist the hose counter-clockwise. Then as it's inserted, it's allowed to untwist itself in a clockwise direction to straighten out. I run the facet for a minute, then remove the wand and cover it with foamed soap, and repeat the process.
