Yesterday was cleaning run no.1 time and as Normandie, it was done outside, keeping a pungent smell out. Guidance below.

Because I had fluted my shotgun output end, I ran it for 30 mins with shotgun on each way round ie 1hr total.
I didn't remove the copper mesh as I presumed (and I have a cast on one arm) that it may as well get a clean too. I thought that I had already cleaned all parts in the kitchen sink, but some flux/residue was evident after the clean sat within the copper mesh as pictured below, unfortunately this staining didn't leave fully, I hope the sacrificial run removes the stain, otherwise I should consider new mesh or cutting this mesh stain away:-
Anyhow, after the vinegar run, I rinsed the whole lot off with an outside hose and a big deep pan of water which pulled much of the flux/residue out, you can see about 1/20th of a teaspoon worth of black debris in the center pan bottom (the brown pan stain is permenant), but some copper mesh stain remained.
This is what may have forgotten to clean in kitchen sink pre-vinegar run as the stain easily rubbed off onto my fingers after the whole lot, perhaps a tea cloth would mechanically rub it off too.
Throughout the whole vinegar run, the temp stayed at a solid 99.3c despite my changing power using my controller to test different speeds, then as I had powered down, I noticed the temp was 95+, this may be because x ammount of water or venegar had left in vapour and changed the boiling point, I do not know as I had only noticed it just after power down.
All in all it was a very easy and satisfying run. In future, make sure you don't forget to pre-clean anything.
