How much does your dealer charge for an M240 sensor clean?

It is hardly the fault of a brush if people try and use it for grease. Did you ever blame a broom if you tried to remove an oil spill from your garage floor with it?

When you see spots it is not always apparent that they are grease.  Not all of us have surgical instruments for examining sensors.  If it is the slightest bit of grease, the Arctic Butterly will smear it on the sensor, and foul itself for good measure.   But you may not see that until it is too late, and you will end up smearing another sensor.   Yes, there is special cleaning fluid for the brush. but I eventually found the whole system to be frustrating compared to the other alternatives.  Visible Dust makes some of these aternatives itself and I have found them quite good.

|I must admit I don't like it too much myself. But if you do smear the sensor because of oil it needed a wet clean in the first place anyway.

But it has been said many times on the forum that with a new camera it should be assumed to be a combination of dust and grease and the sensor should be wet cleaned. Wet cleaning is not an over reaction, it is a simple process and covers all the bases which is exactly what is needed for the initial two or three cleans. The difficulty arises because other methods appear easier, along with the 'I've never had a problem' type of advice that seems to falsely imply in peoples minds that they won't have a problem either.

We are not in disagreement.  My first use of Arctic Butterfly (AB) was not on a new camera, yet there was grease.  I agree that wet cleaning is not an over reaction when rocket blowing is not enough.  I think AB is a clever idea for dust and its static (or anti static) process can work for dust.  My issue is that grease can get on a sensor at any time, not just when new, and in that intstance AB will turn out to be counterproductive, leading to wet cleaning anyhow. Properly done wet cleaning is highly effective and almost never counterproductive. The Visible Dust alternatives I mentioned are their liquids and swabs. I do have the German Eyelead system, but have still found wet cleaning the easiest and most effective.
