I'm driving an 04' Subaru Forester, and it needs some cleaning on the inside. I'm in my apartments underground parking garage, and I'm wondering, am I safe to idle the car (for the AC, lights on without worrying about battery) for ~30 minutes while I clean the inside? It's really hot outside, so that's why I prefer the garage.
Maybe I'm being overly cautious, but, is this enough room to avoid carbon monoxide poisoning? I've always read it's really only a risk in single or double car garages.
