No. Most electrical contact cleaners have additives in them to inhibit corrosion and lubricate the contacts. This will not be good for the board, as it will leave a residue. You need a dedicated PC board cleaner, not electrical contact cleaner.
You'd be better of to simply dry it with the hairdryer, but even that's not a great idea. It'll take a lot of drying to get all the moisture out from under the components (where you can't even see it), and it'll be hard to get it hot enough, evenly enough.
Seriously, most solid state devices are rated for storage temps that go up to 125 degrees C, and operating temps to 85C. That's 257F and 185F.
Automotive devices are rated even higher for their harsher environment.
If you do the CJ trick and heat your oven to 150F, then turn it off and place just the board in there and close it up until it's cooled back down, you should be miles ahead. After all, think about it... if you were parked in Phoenix in the summer with your windows up in the middle of the day, how hot would it be inside your car for those several hours? Yeah, over 125F, at least. It's built to take that.
