Hi,
 
I have a Nauticam macro port 65 that I've been using for a year for the Nauticam OM-D E-M5 housing.
 
I've just noticed there seems to be water drop stain marks on the port glass.  I've tried cleaning these out with soapy water, lens cleaner, and water/vinegar but none seem to help.
 
I don't think this glass is coated.
 
Anyone have a solution to get these stubborn stains out of the glass?  Polishing with a glass polisher work?

 

Also, I'm pretty sure these marks are on the outside of the glass port.

Regards,
 
Jason
 
I've attached photos of the marks.  Saltwater stains?

Normal house window glass cleaner? I've used that previously on a glass dome. Worked for me. But for some coatings it might be too strong. Not sure. Tried glasses wet wipes?

I've also tried window glass cleaner.  The water spots are very hard to remove.  I'm also cautious of harsh chemicals because I don't want to damage the o-ring of the macro port.

I'm sorry to say. But that looks very water burnt. Not sure if that will ever come back.

Do you soak (and I mean for a while, not just a rinse) your housing in fresh water after every dive?

It might be worth sending back for a service / new glass element. Saying that, do those stains effect in water use?

I found some really good glass cleaner. Let me dig it (the name) out for you.

If they are water stains you should be able to remove them with vinegar,

soak a soft kitchen paper and press it on so that it stick on the glass and check every 5 minutes if it dissolves the stains.

 

Rinsing the hosuing and especially the glass/acrylic ports is essential, BUT
even more essential is to dry them after rinsing with a soft towel and take extremly care with acrylic glass as the get scratched very easy.

Instead of rubbing it dry you may dab the water drops with a soft, assorbing cloth or paper.

Try CLR (Calcium LIme Rust Remover), I found it worked really well for removing water spots from my rig:

thetrickster,

 

Yeah, that's what someone else said that it may not be possible to remove the marks.  Though, I would imagine a fine polish should remove them.  The glass still seems smooth so I would think the marks haven't etched into the glass.

I do try to soak my housing in fresh water after a days diving.  There's probably been a couple times I didn't get a chance to soak the housing.  But I do rinse every time.  Though, I do do a lot of beach dives and probably there's been times where I couldn't rinse my housing for several hours.

 

I don't think the stains affect image quality underwater.  Haven't noticed.  Looking through the port with a bowl of water I can't see the stains.

 

Chris,

I've tried a vinegar/lime solution diluted in water soaking for at least 12 hours but that didn't seem to help.  I will try your technique of pure vinegar.

Gudge,

If all else fails, I will try the CLR.

 

Thanks for all the suggestions

Hi Jason

I hate to say this but this looks ominously like marks I had on my Subal flat port after a few months working in the Lembeh Straits in 2009-10.

I tried all sorts to remove them - including consulting Wetpixlers. But no joy. Luckily for me Subal ports can be re-glassed and this is what I did.

I still have no clue what the "bloom" was or what caused it.

That's good work on the water marks... ;) Not sure whether they will come out. One good tip with glass ports is to take a small sqwirty water container on the boat with a mix of isoprol alcohol and fresh water and give them a quick spray if the water is going to dry on it.

TimG,

Yeah the stains seem more like an odd chemical reaction with the glass rather than mineral deposits.  Thankfully, you don't seem to notice them when the glass is wet.  After looking through the glass when the port is partially submerged in a bowl of water, it doesn't seem to affect image quality.

jonny shaw,

 

Thanks for the tip.  I do usually try to keep my housing wet if fresh water isn't available and rinse, soak and dry as soon as possible.

Get some glass wax (or car polishing compound) and use that. You need something a bit abrasive. These don't look like dissolved minerals at all but if they are smooth (rather than etched/pitted) you will be able to clean them with the compound.

Hi Tim,

 

No I didn't. Though I didn't yet try the car polishing solution yet.  You have any ideas?

 

Jason

Sorry, no! I was hoping the car polish would solve the problem for you. At least it would give you a nice shiny port eh?
