My order for "Wash Away" came in. After hearing about this paint stripper here, I have been wanting to give it a try.
Here are the unscientific results of what I found:
First of all, it is very expensive. $18.95 for 16 oz. Plus another $11.33 for shipping.
I had a couple of small pieces to try it out on to see how it compared to my age old stand-by DOT3 brake fluid. If you haven't been following along, nothing else that I have tried ever came close to stripping paint from plastic as well as DOT3...NOTHING!
Upon opening the bottle, I was greeted by what I thought was a familiar smell.
The instructions to "Wash Away' say to soak the part for ten minutes, remove and scrub vigorously under warm water with a fine bristle brush. Rinse thoroughly. Repeat if paint remains tiny crevices.
Before doing that, I wanted to see how it worked on lettering.
I took a Q-Tip swab, soaked it in the solution and started rubbing. Each set of lettering came off in less than five minutes. With the lettering removed, you could still see the remains of heat stamping. 
I then took the car and soaked it for about a half hour. Scrubbing with a toothbrush appeared to take off what little paint there was on the car along with the heat stamping. I am guessing that there was only a clear coat on the car as this is the color of the plastic. Doing this hands on, I was also greeted by a familiar feel to the solution.
That was pretty easy, so, I proceeded on the the next piece that had much more paint to be removed.
This is a partial shell from a Williams Lackawanna FM. Sorry, in my haste, I forgot to take a before picture. There was a Lackawanna logo under the headlights. I first tried to use the swab to clean it off and quickly found out that it was actually a sticker! I peeled that off, then laid the hood in the solution and rolled it over and over to coat the hood, then let it set for about twenty minutes. After soaking, I again started in with the toothbrush. The red was the first color to come off. With more soaking and scrubbing the grey started to come off. Hmmm, this is again very familiar. The paint was coming off with the scrubbing except for the yellow stripe. Not unusual. Things like this tend to be a bit stubborn at times. So, I took the solution and put it in a glass so that I could get the entire hood under cover and walked away for about forty five minutes.
When I came back, more scrubbing took most of the yellow stripe off. It just needed some time to get under that yellow paint. As you can see, the hood came out very clean with the exception of a few hard to get at places where the yellow paint wants to stick. I clean those spots up with a hobby knife later on.
Now, remember that I said there were some familiarity's while I was doing all of this?
Well, I don't know what kind of solution this "Wash Away" is, however;
it smells very much like my DOT3,
it feels very much like my DOT3,
and, it performs very much like my DOT3.
My conclusion is that it works.
It works safely with no harm to the plastics involved in my unscientific test.
It works just as well as my DOT3.
And, it works better than all that other stuff that you guys try to strip paint with!
One other thing. Don't waste your time letting your parts soak for just ten minutes and the wash them off like the instructions say only to find that all of the paint hasn't come off and you have to go back and do it again and again. Let the part soak a while, then start scrubbing with your toothbrush while the part is still in the solution. Work with it until all of the paint is off, then, go clean up with soap and water.
