White paint is staining

I just recently noticed that there are dirt stains on my truck. Mostly from dirty hands.(maybe from the oil in my hands?) I have never had this problem before and I was wondering how to remove these stains.
Thanks

 

Ok ill try that.
Thanks

 

then apply a high quality sealer/wax to prevent further staining.

 

try auto magic white cleaner. Do this after you clay the truck. Don't forget to toss the oil soaked piece of clay. Don't re use it. When your done with the white cleaner use a blended carnauba wax or a sealant. Hope this helps.
