Oh come on pj, this is fun question :>).
John O'R, I use Mr Sheen or some other multi-purpose household
silicone-based stuff (v sparingly of course) to clean the barrel,
making sure that none gets on the glass or inside. I use a lens
"wand" or stick for the lenses. this has a little brush at one end
to flick away dust and a small pad with cleaning stuff inside at the
other end to get rid of grease marks etc. It is a satisfying way of
cleaning the lens. some say that using liquid on the glass is asking
for trouble, as it might creep into the workings. But when I did use
isopropyl (dilute) I used it sparingly with a lens tissue.
Alternatively, if the dust and particles have been blown away with a
puffer or compressed air, a microfibre cloth should be OK for
cleaning away the grease marks.
Whatever I use, I use it more and more carefully now :>).

What is best to use for glass surfaces? and for barrel surfaces?
Any hints, lore?>>>
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.
HTH,
