Hi

Can anyone help me how to clean these Nauticam Wet lenses ? We have 4 lenses from our friends with same issue.

I have sent few emails to Nauticam but did not get any reply.

Thanks

Unfortunately this is a case of prevention being better than cure. This happens when salty water is allowed to dry on the surface. The salts concentrate and the pH increases and eventually it etches the glass.

Some people have reported success using optical grade cerium oxide to polish. This risks damage to anti reflective coatings, so use at your own risk, but there are reports of it cleaning the surface up reasonable well.

To prevent keep the glass wet till you can soak it in freshwater. When you remove it it blow it dry and wipe with a microfibre cloth to prevent the droplets evaporating on the surface. Even the rinse water drying repeatedly will eventually etch the glass surface.

Thank You @Chris Ross

We clean these glasses with freshwater same as our dome port, but there's no problem with the dorm port, I found that all our WWL lenses have this issue with less than a year. we usually do around 150-200 dives per year which is I believe very less.

And also this is design for saltwater and it must be more durable?

Thank You
