Water spillage inside the car..what to do?

[Qashqai]

Today I realized that I forgot to close the lid of my 400ml (13 Ounce) water bottle. It spill all over the driver side rear seat carpet/insulation. I immediately vacuum the carpet with my 12V wet/dry vacuum, but I could get only a half cup of it. The rest is underneath the carper and while insulation layer. Since the outside temperature was -11 C (12 F) the water immediately froxen when it touches (or "fills") the inside of the bottom of the car.

So here are my options:

1. Wait until summer. I will take the rubber mat out and under the Sun, the water will evaporate
2. Wait until spring. Use towel/shop vac to absorb the water
3. Remove the rear seat, inside trim and maybe driver seat and lift the carpet, with a heat gun/hair dryer dry the carpet.
4. Take it to a car cleaner professional.

I am worrying about rust and smell. Do you think I am so much paranoid? Do you think I should leave it as-is and wait until summer? Any ideas? I really need help!!!

I wouldn't worry about it as long as it's frozen there won't be any rust/corrosion or mold growth.

Once it warms up I'd just use some towels, maybe even a Sham-Wow and blot it to soak up the water. Any residual moisture will evaporate if you leave your rubber mat out for a few days. I really wouldn't worry too much about it, I've done this before, actually my wife and kids have done this several times with no adverse effects.

+1 to what Kerrton says.
You don't need to worry about rust/corrosion underneath the carpet since the Rogue's unibody is e-coated to inhibit the build-up of rust.

Just leave it be till the summer, and/or blot up when you can when it gets above freezing.
Every winter my Rogue's footwells get pretty soaked (even with weathertech mats), and I usually just leave the Rogue outside on a sunny, warm summer day with the doors/windows open, and it dries out well.

Or if you have a heated garage you can leave it in there overnight with the windows down and then blot up what you can in the morning...

Thank you very much for your replies guys. I decided to wait until the temperature reaches plus something.
