Hello, and help? (a mistake regarding dew)

Hi IIS people, my name is Matt...

I recently purchased a 12" Skywatcher dob telescope. Its one of those collapsible things so the tube has an opening between the primary and secondary mirrors.

I was using it last night out in my backyard and ran into an issue with a lot of water forming...well over everything except the primary mirror. I persevered with this, not really knowing what to do about it in the short term..

So i do a bit of Google searching and to my horror i read that i should not pack my scope away after a lot of water has formed on the instrument.
Alas...this is exactly what i have done.

I've just unpacked it and had a look over the tube and mirrors and a heck of a lot of water has gone down the main tube part and onto the primary mirror. It looks all streaky and is still damp. so is the main tube

I am really unsure of what i should do about this, and hope that some of the more experienced members can help me outta this stuff up! Should i be removing the primary mirror and cleaning it? Should i just let it dry or maybe apply some warmth near it like a hairdryer type of thing?

thanks,
