1. Could the silencers damaged by this?
2. Should I remove the silencers and clean or am I going to have to wait until the dirt burned?
If mine came with instructions I didn't read them, and I didn't clean them before installation. I'm sure the smoke is just junk from the manufacturing process burning off. Nothing to worry about.
