How to clean road salt and spray off underbody of AS?

Any suggestions on how to remove the road salt and spray from the underbody of the AS? Living in the Northeast - New England this is a constant problem from November to April.

I was considering the self serve car wash but I think the number of quarters needed would be huge.

Thanks in advance

I would simply wet it down, get one of those telescoping washing thingies (professional term), soap it up a bit and rinse it off. I don't think you need to have high fact I'm pretty sure higher pressure will force it's way into the underbelly.

Computers manufactured by companies such as IBM, Compaq and millions of others are by far the most popular with about 70 million machines in use worldwide. Macintosh fans note that cockroaches are far more numerous than humans and that numbers alone do not denote a higher life form. -NY Times 11/91

I suppose you fashion a pvc spary bar and hook it to your garden hose. Then pull the trailer over it. Place a couple of 2x4's beside the pipe where the tires cross.

I agree that you should keep the pressure low to avoid pushing water in to places you don't want it.

We always use cold water to rinse road salts off the motorcyclee. Not sure that it makes much difference but the owner's manual says not to use warm, or hot water.

The thingie would work especially as it would permit the use of soap. Salts will be mixed with dirt and unless you get the dirt off, the salts will remain. There are thingies that attach to garden hoses and ones that are without. We bought a cheapo plastic one—perhaps at Camping World—and it started to fall apart after a few uses at the movable joints at the end parts. I fixed it with a drill and nuts and bolts, so it'll last a while longer. I'd suggest getting better quality than I did.

There are small power washers available that don't have much pressure and that maybe an alternative. However, I'm unsure how long they last. The medium size Delta one I bought several years ago—I think it's 2,700 psi—was poorly made. They replaced the wand on warranty; I replaced the junky hose. Eventually I'll get another brand wand. Anyway I would never direct 2,700 psi on any part of the trailer—it's not like a car or truck. I crank it down a lot or use a garden hose.

The suggestion about using cold water makes sense—hot water dissolves salt crystals into a solution that can be driven into things where the crystals wouldn't fit.

And, salts live on all year, I think. The crystals get ground into the pavement and the spray gets into the dirt alongside the road. When it rains the salt solution comes back like a zombie to attack. When the road gets wet, note the white solution on the pavement for a while. They use a lot of mag chloride here in Colorado; I don't know whether the rock salt used in the NE acts the same way, but I would think salt is salt. There is no escape.

There are RV brushes that feed water thru the handle. That'd be my choice.

I appreciate the ideas for getting rid of the salt.

I do have a brush that sprays water out. I will try that first and I did not know hot water would be a problem. That's why I enjoy posting questions here! There is so much knowledge on this board.

Thank you.
