Can't get all the dust off my UV filter

Can't get all the dust off my UV filter

I tried blowing on it, brushing it, and of course cleaning it with a lens cleaning fluid and a microfiber rug. The dust is still there, on this shot it is highlighted with a light source placed at an oblique angle.

I am worried that this dust might cause veiling flare. Is there a way to get rid of it? Or perhaps it doesn't matter that much?

Looks more loke lint from your cleaning rag.  try a different cloth, and I like a  white distilled vinegar  to remove water spots from my filters just a drop rubbed around with the same cloth, and then dried.

This might be what is occurring. If your tap water isn't too hard (high mineral content) perhaps wash it with a little mild dish detergent, rinse it and dry it with a very clean, hopefully lint-free cloth, or lens tissue. That's what I do with stubborn dirt and smudges.

Have had filters delaminate, giving a pattern somewhat similar to this, but it's easy enough to see surface debris by looking at the reflection on the glass.

Yes, I think this could be it. I'll get a new rag tomorrow, and I'll keep your vinegar tip in mind. Thanks!

Something else that works well are those disposable spectacle wipes.

I use these wipes for my lenses.

They dry in a few seconds, so there's no need to use a cloth afterwards. They're inexpensive as well.

This stuff seems to be moving around, so it's definitely not delamination. Thanks for another tip, I'll have to get a new microfiber cloth in the morning, and find out if this lint decides to be stubborn about staying or not.

I use these also, they work great (my local WalMart has them in their optical department).

Re: Can't get all the dust off my UV filter

that isn't dust but I'm gonna take a guess and say tree pollen which can be very sticky.  Using wipes and/or/plus a good screen cleaner should take care of it---also get several micro cloths to use.--Aren't ya glad you got it on the filter and not the lens     ----------ron s.

for all optical cleaning, I use these.  I can get them from my local optometrist, also use them in the lab.

To the OP:  If none of the above suggestions work, just buy a new filter.

A few dust particles remain, but I don't think they dispurse enough light to create a noticable flare.

I bought some single-use lens cleaning fiber paper from an optitian (thanks Paulmorgan for the idea), and cleaned the filter in the usual manner, by spraying it with a lens cleaning fluid first, and cleaning/drying it with the microfiber paper. I also put the filter under running tap water for a few seconds, just for good measure (before the previous step).

So it was it was loke lint, as ambert4 suggested. I bought the previous cloth in a reputable store, so this is a bit weird. I guess I'm now blacklisting the brand. Thanks for the help!

Success!

Thanks for following up. We all learned a little, I think.

Cheers,

You will not see it in your images.

So I would not bother too much. Wash it, wipe it off with silky cloth, and be done with it. What is there, will be there.
