Interesting note in the MD 500 POH they specifically prohibit the use of Simple Green due to it's corrosive nature. try a soaping mix of Dove and water.

Typically we just use an "Automotive soap" in water. There are tons of brands, some have "wax" in them to leave a bit of a shine.
IIRC, I tend to use a "Mcquires concentrated" (sp) for cars & aircraft. Just try to NOT do it in direct sunlight. A cloudy/rainy day is great.

Most "liquid dish soap" tends to strip any wax off the surface (not saying there is much to begin with....).
After dry, "Pledge" is a sorta cheap way to deal with a better surface, some of the "spray on, wipe off" helps cleaning after.
I REALLY shy away from the "miracle polishes" (Nu-finish, etc) since a lot have silicone in them, thus repairs/patches down the road don't stick well.
