I have ordered a set of Opticlean last year, the price was USD95, as
it advertised, it can clean hundreds of small lens surfaces. But it is
very hard to work on, the coating is very difficult to peel off. You
have to use a sharp point tool to peel off an edge before the whole
coating can be removed easily. The tape that come with the kit for
removing the coating does not work well, most of the time it cannot
lift up the coating and it will leave residual on the lens surface if
it touch the lens surface. If you paint the polymer over the lens
element mounting ring, that is a tragedy, it will take you a hard time
to remove it. That means you have to avoid the edges of the lens
element and hence they cannot be clean with the polymer.
Besides the above problem, it do clean the lens very well, no any
dirty can be seen even under strong illumination, very good for
cleaning the elements inside the lens (but removing the coating is
difficult as state before). I don't think you need it to clean the
outer elements, because they will trap dirty very fast and this
ultimate cleaning does not last long.
