Having bought a Jet Clean system for my razor, I was a little surprised to find i) it needed a special cleaning fluid and ii) the jet clean device did not come with a "starter / sample pack" of fluid. So I had to buy some. Found Amazon to be the cheapest source (when considering P & P costs) and bought a bottle. The Jet Clean system plus fluid certainly does the job but the fluid seems to be very expensive for what it is and needs changing potentially monthly. I guess a bottle of fluid will last 2-3 months, used prudently. It must be possible to find some cheaper alternative. Not sure how long I'll use the system for but having "invested" in the Jet Clean, I'm a little reluctant not to use it.
