Dave,
I've used a sable brush and a micro-fiber cloth for years to clean lenses.
Zeiss, among others, sell them and they work. If you are worried about a
micro-fiber cloth damaging your lenses, here is a quote from the M8 Instruction
manual, page 126:

If that doesn't do the job, I use a drop of what my Leica dealer uses on his
Leica lenses: ROR Lens Cleaner. ROR stands for Residual Oil Remover. See

All the best,
