If you have it easily to hand, could you post a link to the guidance please, or a search term that will find something suitable. It would be good to know what I should be doing. Thanks.

Would it be worth experimenting with a more direct stream of application rather than a misty (atomised) spray?
I think DB showed a plastic container with a metal needle nozzle recently that looked a good idea (plastic nozzles suffer).
As my lathe tends to sit for weeks unused then get used a lot & then resting again i use a straight synthetic cutting oil, Crowncut 810, nice to use & leaves the machine clean & shiny. The same oil is in the tank as when i filled it 5 years ago. At College the other technician filled the tanks with Ilocut, horrible brown tuff that oxidised & left the machines covered in a case of thick brown crud.

That horrible stuff must be what was in my lathe, it came from a school/college

I never really have issues with any soluble oil although I prefer some more than others and I much prefer the translucent than the white, especially on the Chiron.
The last stuff I got was fully synthetic from lubetech oils on eBay, can't recall the name but they do not do it anymore for some reason so I have just purchased some Rocol V-Cut SS which is as detailed below.
I always use tap water but then again our tap water up this way is different to the stuff you lads get further South
BTW the Rocol was £90 plus VAT but with the dilution rate they say it should work out pretty economical which is a word I like

The difference is quite frightening really.

Aye, it is probably the reason they are a strange bunch down there

Wow, so many informative replies!
I had never considered using distilled water. Seems a little off the wall for something that's circulating over sometimes dirty, sometimes rusty steel and over surfaces out in the open all the time - especially in the cold saw. But it's a cheap experiment and could get me to use up the S/A fluid. Can't say I've noticed anything off/stale about any of it though to be honest.
Perhaps I'll make up two small batches to put on a shelf for lobger term comparison.
I occasionally grab a bottle of "penetrating oil" (~1:1 kero & ATF) but that smokes for fun so is likely neither a good coolant nor good for me. Potentially an issue for all completely oil based things?
Don't have any major issues with gummy deposits, yes they are there but I can cope with that.

Ours doesn't. But is UV'd.
That won't help.
I used to live in a house with water from a spring. UV lamp in the system. Still noticed a build up of mould in the washing machine drawer.
Best add a touch of bleach to inhibit mould unless the fluid already has a biocide.

Could add a spot of sodium hypochlorite into the that should keep any bacteria and mould at bay, I guess you'd need to be careful of the concentration though as it could potentially damage aluminium cooling pump parts if too strong.
They always do. Give mine stir before use.

Bacterial growth will almost certainly 100% be a problem, but not a cause of the separation
