Quick detailer/bug remover recommendation

[vitaly]

What product(s) do you guys recommend for those spot/ad-hoc detailing situations? In particular, with bugs abound, what do you use to remove the bugs (and bird crap) in between your normal car washes/details? I'd like to keep something in the car with me, but would obviously prefer that it doesn't blow up when the interior temp rises (e.g. sitting out in the sun) .

Optimum No Rinse is one of my favorites...

I use Ultima Waterless Wash Plus.

Thanks guys. A bit more research shows others are quite fond of ONR as well, so I've gone ahead and ordered it (with the wax mix though).
