Some windows look like pvc but are actually powder coated aluminium. Also, some PVC windowsleaves have rubber edging that leaves spots.

This is absolutely correct. Some windows have painted aluminium inserts but it looks like uPVC. It can be very deceptive. By the time you can see milking it has to be pretty serious, a lot of times it is happening but you don't see it

When ever you get spots check the top of the frame by rubbing with your finger and checking for white coming off.
Also, look at the pattern of the spots. You can usually see its running down so its drip related. Or its splashing down from above having come off the brickwork or sills above.

Spots don't appear out of thin air. As I have learned through many such problems there is always a reason for it. 

Hot water speeds up this removal process IMO. Problem windows...use cold water.
Have to agree that if it is breaking down oxy then hot will speed it up as it eats in more, think of it of washing up in a bowl of cold water yes it will get rid of grease but will take longer, hot water eats through it quickly. thats IMO

Some frames (most?) come good after a few cleans. Presumably this is because all the loose paint has gone. So my technique of trying to avoid disturbing the stuff is probably 100% wrong.

Perhaps its better to bite the bullet and try to get rid of it.?

Thats my method ;)

I scrub everything I can.  Scrub until it runs clean and clear.

LWC, Surely you take a water reading on a regular basis, to make sure the water you are using is at a acceptable level for cleaning windows?

Are you sure then the meter is working properly?  If the TDS reading is 1, and the meter is working properly, then it shouldn't be causing the problem on the glass.
