I've had my FX armor for 8 years, and over that time its had its share of dings, scratches, and most noticeably, black scuff marks from either my painted blaster or from my boots being stored too close to the armor and rubbing up against it. There's also a few spots of velcro glue from my first attempt at putting the armor together.
Wanting to give my armor an overhaul, I came across a wonder plastic cleaner----paint thinner. It's still sold for cheap in the old fashioned large metal container. It goes without saying to use this stuff in a well ventilated area and not to use it on painted armor, and it's best to try it on an inconspicuous area first.
I used paint thinner and a soft cotton cloth to clean up all my armor and never did I see it react with, nor soften, the ABS plastic that the FX is made of. It did not harm the plastic even when using generous amounts of thinner on the cloth and rubbing the same area vigorously. It worked wonders at removing the glue, black scuff marks, and most if not all other blemishes. It will not repair scratches, but if your scratches have accumulated dirt/grime, the thinner will clean it up. The thinner worked so great, my armor is very shiny again.
Just wanted to pass this along to everyone!
