What do you use for just spot cleaning some dirt or other junk? but not the whole car?

I would have thought to use some Quick Detailer, but now I'm thinking they're more like waxes to be used after a wash, so I'm wondering if that's the right thing.

Maybe ONR? Or spray some diluted soap on it and just wipe off? I'm thinking something like P21S Total Auto Wash would be too harsh for just a little smudge?

Thanks in advance!

 

A QD or Spray wax will do. Always have it handy with a mf towel.

 

I love ONR for spot cleaning. Always carry a spray bottle in the trunk as Moe said for those unexpected bird droppings.
