For fresh "gifts from above", I tend to just water (the warmer the better if at all possible) through an adjustable trigger spray head so you can adjust from a jet to get most of it off to more of a fine mist to "rinse" the general area. If it's been on the paint for longer though it usually needs to soak for a minute or two first.
Failing that, any QD or waterless wash should suffice with a soft microfibre - I know both CG Speed Wipe and Eco Touch Waterless both work okay. Again it's best to soak it for a minute before wiping it away. Depending on which QD you use, you're likely to add a bit of protection if anything, so perfectly wax safe.
I've got a little bird @*!# kit in the car with a small bottle of 50% diluted APC, eco touch QD and a microfibre and most importantly some tattoo gloves I use for detailing.
Got one hit today at work, can't have been on more than a few hours (though it's been baking hot today) but after gently lifting off, there's still an etch left behind. Was hoping for something PH balanced to help deal with the invisible nasties this?
If it's gotten to the lacquer, thats three layers of protection its eaten through in one afternoon, god knows what these birds eat round here
