Washing bare aluminum trailer to shine?

Hate to break it to you but the only way to get rid of those streaks is to polish it. And don't use anything stronger than a mild soap to wash it with when you get rid of them. Now you understand why most people just flash aluminum and forget it?

 

There are some ‘citrus’ based degreasers and cleaners to work pretty darn good. Won’t be quite as shiny as polished or buffed, but for road trucks………….

 

Citrashine is decent for cleaning without ruining the shine. But for it to really shine. Better break out the buffer and the wax.

 

That’s why last trailer i ordered had white rear instead of shiny, looks good unless you haul nasty product and when it’s washed it streaks down and looks horrid.

 

Most of the streaking is due to the standard industrial truck wash’s hard soap and water along with hi pressure hot water rinsing
I have managed to beat a lot of it by
Spraying doors down later with simple green….let it soak….rinse gently with cold water…then use a better dish soap and brush again gently cold water rinse works best
But chances are ifn you tea want it right…,gonna hafta polish
