My reply:
Oh no!!! Not again!!!
I urge you to search the archives. This topic comes up very often.
There is no consensus, but I use 99 0sopropyl alcohol from the drug store
and cotton swabs or old cotton T-shirt. I stay away from the 70 0sopropyl
because it has all sorts of other listed ingredients and use cotton because
paper products can have fibers that may scratche elements.
Also, I hope you are talking about cleaning the front and rear elements and
not taking the lens apart. Unless you have a _very_ proven method of
controlling the dust, I would leave this to a professional.
