I tried the sensor cleaning... no effect. I've got cleaning disabled on startup / shutdown at moment.[/quote]
There's no reason to disable this feature.

Now that I think about it, I can only check back to light background photographs without spots which were taken just before I forgot to switch camera off before changing lens. Duh <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='

I was sitting on a bench near a small stream - there was no splashing as far as I can remember. Other than that, I can't think how it would have got moisture spots in there.[/quote]
The sensor is well hidden behind mirror ans shutter, there's no way how moisture could have gotten on the sensor during a lens change.
As already said, usually those spots are dust, not moisture. And it's quite normal for a digital camera to selct dust spots over time. That's why automatic sensor cleaning is built in.

Before I get to that, would you recommend trying blowing it out with compressed air..? (Although I don't have an AC adapter to lock the mirror up for cleaning if I'd need to).

NEVER use compressed air. And all you need is a fully charged battery to lock the mirror, not an AC adapter.
