[LRflex] Re: formula for lens cleaning fluid

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,

Bill
