I did a test today on the standard A-Wing- Simple Green, Pine-Sol, and finally Winsor and Newton Brush Cleaner. -Simple Green/Pin-Sol- both were really good at taking off the wash. If it even budged the paint a little, I didn't notice it. -Winsor and Newton Brush Cleaner- I've seen multiple tutorials about using this, so decided to try it myself. I started sparingly- booooooy howdy, I'm glad I did. It took the wash off upon brush application. After leaving it on for less than a minute, the grey panel paint finally started to budge. After some more waiting and rubbing with a cleaner-soaked q-tip, the red finally started to go. Awesome, progress! Well... not so fast. I had the bright idea to run it under some warm water to help clear off the quickly gunky-paint. Well the water seems to react with the cleaner and solidify the paint, making a tacky mess. Not good. I quickly soaked another q-tip in the cleaner, and re-applied. The gooey mess came up off on the q-tip no problem. I spent another five or so minutes using a q-tip to clean up the remaining goo, alternating between a dry and lightly-cleaner soaked swab. Once the goo was all up, and I could see the panel lines were clean, I grabbed some Ajax brand liquid dishwasher cleaner and applied it directly to the model. I scrubbed the model down, and the goo came up with little trouble. A little rinse in some running water and everything came off. I was left with a nice, clean bright white A-wing. Lessons learned: If the model has a thin coat of paint, you might consider just cleaning off the wash with either Simple Green or Pine-Sol or something similar, base coating and painting. Or skipping base coating. Whatever you prefer. If the model has a rather thick coat of paint, or you're like me and just prefer to start from a non-painted model, Windsor and Newton Brush Cleaner works really well- just use it sparingly. While it didn't melt the model on mine, I think given enough time and saturation, it would begin to eat at the model plastic. I removed the A-Wing lasers, just in the event the thin plastic reacted with the solvent. So there you go. Hope that helps!
