Small Scale Military Headquarters

Got some issues with a BBI F16 wolfpack.
Landing gear tires and exhaust nozzle are sticky just like I 've removed some stickers and bit of sticker glue still remains on the parts.
Everbody got the same Problems? Is this a chem. reaction on the plastic/ Rubber parts depending 8n time and dust???
Is there a better solution like washing with water and soap or alcohol or something else???
Thank you for helping.

I had the same problem with a BBI F-16 I bought years ago. I used a teaspoon of baking soda mixed with water until it formed a paste. Using my finger I rubbed it in circular motions on the problem areas. I cleaned it off with water and a soft cloth. I read about this problem and its solution back then. According to what the article said this happens with certain soft plastics as they breakdown over time. Hope this helps.

Thnx Rudy
