Removing bad stains from a trailer?

[robfrey]

What a mess. This is my father-in-law's trailer that he basically bought for stirring stuff that does not fit in the garage. He bought it stained like this but it had gotten worse. It is not parked under any trees at all but might have been at some time. From what we understand the trailer came from CA.

Any ideas on how to remove it. Buff the front but I'm actually buffing through the white before stain comes off.

Any RV shop should have black stain remover, just do it in small sections, Spray on and use a soft brush.

This stuff seems to be working best but it does seem to eating the finish. Maybe it is just because the finish is so far gone?

Mine gets diesel soot on it.  It won't come off with normal soap and water.

WD 40, house broom, then wash like car.  

If not, soapy brush at pay wash.

Thanks Glen! I will try an RV shop tomorrow.
This simple green stuff seems to also be important to only do a small spot at a time and not let it dry. Also seems to work best if sprayed on a dry section. This is a bit challenging as you must bounce all over to place to find dry sections with no water splash from the previous rinsing.

Wish I could get diesel soot on my trailer. That would mean we had a diesel truck, of course.

I love Simple Green, however, it does have the ability to permanently discolor alum in some cases.  Not a little, a lot of ugly.

Pink Stuff or as Wal-Mart, Tractor Supply, etyc. sells it, Purple Power. Its like $6 a gallon , I use it for a ton of stuff from spraying my hands down in the garage before comming in the house and on from there

SIMPLE GREEN IS ACTIVATED WITH COLD WATER. i USE A HUDSON SPRAYER WITh 50% SIMPLE GREEN AND 50% WATER.

Sorry about the caps.

B52 (I think thats what it is called) is another good one

Haven't tried it on a trailer, but Purple Power is what I use in my degreaser tank instead of solvent.  Works VERY well.

Rob,

If you have 5 minutes, you can read this thread on a RV forum. Seems like different products work for different applications.

Thundersalt on this forum could give some good advise for this question, as Brian owns a RV repair shop.

Hope this helps and good luck.

Tom,
Thanks. I was looking for a thread just like the one you found.
Our staining was so bad. I think it was a combination of the aluminum band and the acid rain and the neglect for many many years.
It was a probably exasperated by the finish being so oxidized that the finish absorbed the black staining substance. Simple green took off the stuff eventually but it also took off the finish in some places down to the green primer. Still, looks better than it did.

RN solution--- Roller brushes & KILLS--- then new exterior white house paint
