HOYA HMC surface cleaning

[i120D]

hi,
read a few complaint about the HMC surface being fragile, any experience?
where the coating get smeared when being cleaned, any solution or secret recipe needed?
now considering whether should invest into B+W instead, if the work for HMC is really that troublesome....:dunno:
understand the quality that comes along, but can it be justified by the higher price of B+W?
pls help....

Hmm...if you wear spec you should know of those ultrasonic cleaner in reputable specs shop. Give it to them for a ultrasonic clean!

I got one industrial unit at home
don't worry about the water, they won't cause fungus on such thin single piece of glass.
