Plastic models — clear parts in particular — can get dirty on display, or even while you’re building them. Dust plus smudges from handling can build up and dull any finish.
Instead of heavy-duty cleaners, soap, or other substances that can mar a finish or alter the color, I like Permatex Fast Orange. Sold as a hand cleaner at auto-parts stores and general retailers, it is mildly abrasive — just enough to rub away dirt or liquid stains without abrading a plastic surface. Used gently, it doesn’t scratch paint, disturb decals, or damage clear styrene.
Put a bit on your index finger and gently rub the surface to be cleaned. (Before going whole-hog, test an area of the model that’s the least visible.) Rinse with clear water. Depending on the subject, you can hold the object under running water or wipe with a dampened tissue or soft rag when you’re finished cleaning.
Fast Orange’s gentle power isn’t limited to plastic. I had an old vinyl motorcycle someone had painted with black enamel. I tried Fast Orange, and it removed the paint without damaging the vinyl. I used more pressure than I would have on plastic, and worked a toothbrush into tight spots. When I was finished, the toy was its original green color.
Fast Orange also works well on metal, faux wood, and glass. And, yes, it is also a pretty good hand cleaner!
