A scent that smells like Oranges would be nice, most everyone out there loves how oranges smell. It probably will cost a lot more.
Here is an odd question Russ, if you could get an orange scent, do you think it would be stable in a truck wash soap? Aluminum brightener? And not weaken the mix or leave a residue on new, shiny aluminum trailers/tanks/wheels?
I would not mind adding this orange scent to some trucks I wash if it was available and did not damage surfaces or aluminum in any way.
People would do double takes and think a lot if they smelled garbage trucks and other large trucks that smelled like oranges going down the street, it would be funny to hear how they like the smell of the garbage trucks in the morning. hahahahahahaha
