Couple of things to keep in mind ...

If the brush does get contaminated then it's dead easy to clean - simply pour some IPA (Iso-Propyl Alcohol) into the hard plastic cap - insert the arctic butterfly - and give it a few short bursts.
THEN LEAVE IT SOMEWHERE FOR A FEW HOURS TO DRY (or even overnight).
Be aware that it's a great solution for most dust - but - wetcleaning is still sometimes required - and the 7x Loupe helps a lot too (finally got mine a few days ago). So yes - the products are expensive - but then again, Canon charge about $125 for a clean in these parts - so it doesn't take too many of those to exceed the cost of the entire VisibleDust suite of tools.
- Don't operate the motor to dry it quicker (it dries it really well, but it'll leave the bristles all splayed out), and
- Don't put the brush anywhere near the sensor if theres any possibility of it still being wet with IPA.
- If you can, test it for smears on something like a clean lens front element first (saved my butt - I suspect someone at the store ran it across a finger to see how soft it was before it was sent to me).
