Maintenance of Nielsen Sonic and Paradox silencers

How do I correctly perform maintenance on my Nielsen Sonic or  Paradox silencer?  Maintenance of a Nielsen Sonic or Paradox silencer is relatively simple:
    • Clean sparingly and only with a piece of cloth and oil.
    • Make sure the silencer is completly dry before putting in storage.
    • Give it a whiff of WD-40 or similar up through the back end.
    • Avoid ultrasound cleaning and basic cleaning agents.
If the silencers needs a good cleaning, our best advice is to take it to a shooting range/cinema. When the silencer gets moderatly hot, the excess soot and the likes inside the silencer get burned off. Be aware not get the barrel too hot in the process.
