A customer of mine has some trailers with some foam substance on the outside they need off. The foam was used on the inside of a refrigeration trailer and leaked through. There is also some sort of residue on the galvanized rears of the trailer. Any ideas to get this off????

Is that expandable foam similar to the stuff you buy in a can? If so, that stuff is horrible to get off. Only thing I know that might take it off is a solvent. When I get it on my clothes I just throw them in the trash.
 
It's the stuff they use to insulate the walls to make a standard trailer a reefer unit I'm heading over there this morning with an arsenal of chemicals and tools to try and get it off. I have everything from glue remover to just 3000psi and 250 degree water. The shop it's at says they have tried everything and can't get it to budge but I love a challenge. The sales rep for vangaurd told me I would be The Man if I can fix it. Wish me luck!!
 
I agree a solvent may take it off or something like goo gone or delimonene (don't get it on the decals). Thats a product that is not designed to dissolve easily so good luck.
 
Leave the solvants alone if you get them on the polished doors it will be a more noticable cause its on the back.I would take a small sander over there start out with 200 grit then move to 400 grit paper and it will really smooth that aluminum rail out and in the process it will take that stuff off as well.
 
A friend was using that sprayfoam in a can and got it on his hands, that stuff would not come off. He tried hand cleaner, paint thinner, gasoline, diesel, goof off, just about everything he could think of but that stuff would not come off.

It wore off his skin in a few weeks, his hands looked very strange and dirty until that stuff wore off.

I don't think you will find anything to get it off the metal, Hal has a good solution, sand it off or buff it off and do the whole section so it is even.

There are just some jobs that you can't do or don't want to do no matter if it could make you the hero, the downside is that it can make you look very bad if something gets screwed up. As nice as those doors are, I would not take a chance. Maybe recommend a metal polisher guy can polish it out.
 
Great stuff from the can melts with acetone, then wash your hands and your good. No idea what it would do to polished metals, but it may be worth a small shot.
 
Start at 200 grit and go to 400 hundred i wouldnt lead you wrong fellow fleetwasher I promise.The the metal polish will not work unless the aluminum is smooth.After you sand a bit then use the polish

Thanks Neal. Do you know what acetone does to Dickies pants? I usually get quite a bit on mine.
 
It would probably melt some, just getting the acetone out of your pants would suck, too. Wouldn't want to wash them with the unmentionables I would think!
