I just want to stop you from recommending a defective product and in that sense, yes I do want to win as unsubstantiated recommendations are dangerous recommendations which can and will cause harm to others.
Now, folks who read this thread will know that using Acetone has it's admitted shortcomings, based upon the safety/information links you and I both provided and they will also know that Acetone should be used with care as to issues of safety in regard to their filter and photo gear as well as personal and environmental safety issues, even if Schneider Optics states that they feel comfortable recommending Acetone as a product of last resort..... with caveats of course.
You may not care about harm coming to others, I do.

As a new glasses wearer, I initially tried cleaning my glasses with a microfiber cloth with or without cleaning solution. Over time, I find that this often leaves streaks and they get dirty again fairly quickly. Better I have found are the disposable wipes for glasses. They clean well, leave no streaks, and the glasses stay clean longer.
I would assume that they would be safe to use on lenses as well, as long as dirt and grit is first removed with air or a brush. They work so well that I am a bit surprised that I have never heard them recommended for camera equipment, so I thought I would jump into the fray and offer my 2 cents worth.

wlachan, acording to the link you provided, you are right. Acetone will not hurt camera lens multicoating.
To all others, do not use acetone except as a last resort, perhaps for example if you get paint on your glass. For such a use, be very careful not to let the acetone get on any surfaces that are not multicoated glass, because acetone can be corrosive to plastic, rubber, adhesives and paints. Also, it is quite toxic so use it only in a well ventilated area and avoid skin contact. If you ingest any, or get any in your eyes, see a doctor immediately. Also, do not travel with acetone as it is a hazardous flammable liquid.
(I'd like to express my great appreciation to wlachan for confirming that acetone is harmless to camera glass multicoatings. wlachan is such a smart and helpful fellow.)

your breath (stinky or not) and any house-hold tissue paper will work. done it a few hundred times without any problem. brush off the lint and you're done. you can also use lint-free (kimwipes) paper if you want to get fancy...
methanol, ethanol, isopropanol will all work. these are solvents, which will help to disolve the grease/oil (ex. in your finger prints). they also dry faster than water. they will not affect lens coating. woulnd't use acetone!

HEY EVERYONE!!!!
Just to let you know I have an old lens that has a broke autofocus and I never use it. After an experiment I can tell you ACETONE IS NOT SAFE WHAT SO EVER. Lets just say my coating is ruined.
, I have a few old bad lenses that I will donate to the name of science, what chemical will we try next?
