Misty / Moist Hoya Circular Polarizing Filter

I have a Hoya Circular Polarizing filter that has either moisture / mist between the glasses around the edges.
I bought the filter as part of a bundle of used items so have no idea how it got in there or what it is. The filter is however apparantly only a month old and the seller is happy to have it back a to try and get it replaced.
I was wondering however if you get some form liquid or mositure between the glasses of filters like this is fit for the bin or is there a way of drying it out, for example a hairdryer??
Grateful for any thoughts.
Thanks, Andrew

Do you have access to a Rayburn or Aga range cooker or similar? If so you could leave it in the warming oven section - this should dry it out pretty quickly without damaging it. If not, we have one so you could bring it with you when we meet?

I think I would first try putting it in a bag with a few packets of gel crystals - put it in a warm place and see if you cam draw the moisture out

Silica Gel sounds the most likely candidate you dont want to create more moisture by heating,well I would not have thought

Heating will not create moisture.
Warm air will hold more water than cold air but in a sealed system (like the recommended bag) you won't get more - but you should transfer some of the water from the filter into the air, where the silica gel can then absorb it. Carl's suggestion should be ideal, unless you have access to a vacuum oven/dessicator (unlikely). I'd recommend keeping the heat fairly low though to avoid possible damage to other components. ~50°C should be reasonable.
Without the silica gel, you might just redistribute the moisture, but even that should allow much of it to be wiped off the outside.

Thats is what I left out Mike

Point of order: desiccator

Sorry, that's a pet peeve of mine, I'll get back into my box now...

Thanks all, I think I will have a quick go and see what happens!

Rice is also good for drawing out moisture.

Strangely enough so is cat litter ,sounds odd but it works

Andrew, don't buy from a scouser! Hee!Hee!

Perhaps Jan we should let other members know just what you did? Or shall we keep that a secret???

Andrew,There is only one thing worse than bad publicity -- no publicity at all. I don't care what you say about me, just make sure that you spell my name correctly. Publish and be damned, let's give everyone a giigle.

Jan, I am no grass!
