    I guess this means the supply of people willing to pay a hundred bucks for
    a brush is dwindling, so they're branching out into the area of "brush
    accessories". After all, any brush that costs a hundred bucks must need
    a bunch of accessories!

    Reminds me of an ad I saw recently for milk that actually said "now
    with calcium".

    Gee, what will the advertising agency come up with next?

    Made the mistake of not cleaning a brush I used and it took a half dozen wet
    cleanings to get what they refer to as SIZING off the sensor.

    After leaning to PAY ATTENTION when someone says clean the brush, I have been
    getting the sensor clean in less time than it takes to talk about it.

    Brush: $2.99 nylon FLAT WEDGE SHAPED eye makup brush purchased at CVS Drug
    store (it looks identical to the brushes sold by visible dust)

    1.Washed brush with Ivory Liquid dish detergent in warm water

    2. Rinsed in distilled water 4 times
    air dryed.

    When blown with dry air or canned air to build a static charge, it will
    remove all dust/hair (thats what I had - HAIR! on the sensor) in one pass
    over the sensor in each direction. (one left to right one right to left)

    Also, the brush works wonders removing dust particles from the mirror and
    focus screen, should any get there. (I use a second, seperate brush for this)

    After cleaning the sensor, I simply blow the brush off with compressed air
    and store it in a (c) Zip Lock bag.

    I have a compressor/air dryer at home, but for remote photo shoots I now
    bring a can of air with me (3$ at Radio shack) in case I need to "charge up"
    the sensor brush.

    Im not "Anal" about it, if the dust mote can be fixed with 10 seconds of
    clone tool I leave it 'till Im home, but if its a "BIG BLOB" I'll clean it on
    site.

    Well, you do want to make sure you keep any brush you're using to wipe
    your sensor very clean. If you touch the bristles with your hands, for
    example, skin oils will be picked up by the bristles.

    That said, cleaning need only consist of washing the brush out
    thoroughly with dishwashing fluid, rinsing well, and allowing to air
    dry. No $10 magic cleaning fluids required.

    As another post here said, just be carefull when you buy a brush, as
    most have 'sizing' in them (keeps them looking stiff and pretty on the
    store shelf), which may require repeated washings to remove before first
    use.

    I picked up a set of 'sizing-free' brushes inexpensively on eBay (eBay
    search on 'sensor brush'). A couple of iterations of canned-air blast
    followed by quick, light swipe of the sensor and dust bunnies are gone.
    Haven't had to do a wet cleaning since I got them.

    Well informed sources tell me that the main ingredient in the sensor
    brush cleaning solution is highly purified snake oil. Or was it snake
    pheromones?... but that might be another product.

    The only liquid I use in a "wet cleaning" is Lab standard distilled, de-
    ionized water. (I can have as much as 5 gallons a day from the lab at work
    so I never run short of pure water). If you Only use pure water, you wont
    leave any residue behind.

    I heard you can make great coffee with that water, my friend used to work in a
    horse urine lab and he could get the water. (Never tried the urine...)

    Well I never said don't clean the brush, but $1 for a fancy detergent tablet?

    Hey, maybe an effordent tablet would work!

    I put a few drops of liquid baby soap (no additive perfumes) in a cup and
    pretend I'm gonna shave Clint Eastwood with the soap cream! Then I rinse the
    brush till there's no soap left, and put it into a plastic bag like you - good
    idea!

    I agree about the 1 dollar detergent tablet...

    Maybe we should get together.. you make the soap [[ NOW IN A CONVIENIENT
    LIQUID FORM!!! ]]

    I'll get the brushes, and we can sell them as a set: two brushes and a small
    vial of soap only 55 dollars (US) cash or money orders only please!

    That would be about $6 our cost for a neat 49 dollar profit. We gotta charge
    at least $25 for shipping though.

    If it is dust y'all are concerned with, all this will be need to be done in
    a Class 100
    clean room (your part plus the consumer's sensor cleaning). Oh, I see tons
    of consulting
    work on the horizon!

    As I said, the eBay brushes do NOT have sizing in them, and so require
    no washing upon receipt. I did the 'filter' test when I got them, and a
    thousand swipes on the multicoated filter revealed no residue whatsoever
    (OK, I'm anal about such things).

    No, it makes wretched coffee. Good coffee requires a certain mineral
    content to the water. The SCAA has pretty specific recommendations
    concering this. Also, deionized water will trash the aluminum innards of
    most coffee makers.
