Anyone Wash Coal, Asphalt or Petroleum Coke trucks?

[Christopher]

Just looking for some advice here. I am bidding on some trucks that haul all kinds of stuff but I have not cleaned any that have hauled Petroleum Coke. It is kind of like coal and asphalt. It leaves a bad stain/residue on the surface and it gets into the pores of the aluminum trailers.

One guy locally blasts them with a turbo nozzle to get some of the stuff off but then uses straight acid/aluminum brightener on them to get them clean.

I was wondering if anyone has cleaned anything like this and what process/chems you used to get it clean.

I am thinking that there has to be something better than straight acid on aluminum to get it clean.

What do you think?

I know of nothing that will clean bare alumu. better than alumu. bright.,I think anything else that would be strong enought to clean bare Alumu. would burn the alumu.

olive oil with a pump sprayer let set and go to next truck and come back with hot water and it come off then put the ab on

I am working on trying to find out what would work for these trailers, they have around 60 of them. If that olive oil worked, I would probably need to get a 55er of the olive oil, just do not know where they sell it at in those large sizes.

How long have you been doing trailers with the olive oil?

Do you have any before/after pics to share?
