I washed my car on Wednesday. And I drove my car to work on Friday. After coming back home, I noticed that there was yellow-ish splatter at the bottom of my windshield!

I roughly examined the paint, and there didn't seem to be any bird poop on painted surface. I couldn't be sure though as my house faces west - during sunset it is difficult to examine the paint.

I was wondering what my options are. Should I do a full wash? Or can I just wipe down the car with QD?

I drove the car about 15 miles on Friday over the duration of an hour or so. The car was parked indoor. My car is always parked in garage at home.

I've never done QD wipe down.... Is it just as simple as spraying the entire car with QD, and wiping it with MF towels? I would appreciate any input

Thanks in advance
