It was developed primarily for military use. Due to the excellent test results of the scientific institute of the Federal Army in Germany, even special forces are now using Robla-Solo-MIL. Robla-Solo-MIL consists of a special combination with ammonia, which dissolves not only fouling from copper, red brass and zinc, but also lead. Steel, chrome and nickel are not affected by Robla-Solo-MIL.
In the case of heavier metal deposits, it is possible to fill the barrel, which is closed on one side with a cork or rubber plug, with Robla-Solo-MIL and let it work for several hours, preferably overnight. For lighter fouling, it is sufficient to pull through several times with tow impregnated with Robla-Solo-MIL (Sucol, Sucolin or Sucolin Extra) or with a felt roller.
