Top critical review
Ok but poor value and not as good as description states.
22 February 2013
D800 had some dust, loose material and splatter on the (CCD)filter, thought these would do the job going on their description.
Did an OK job of removing the loose stuff, did not remove much of the splatter and left a film of residue after the 2nd attempt.
Used 3 swabs and half the solution but it got steadily worse.
Ended up using the last swab with a dab of distilled water to rinse, then made my own watered down solution(with natural household cleaners)to remove the film left prior. (Think cleaning a mirror with something not designed for glass, I'm sure you get the picture, this is what I was dealing with).
Rinse and repeat, finally got rid of the film and got the filter much cleaner. Went from about 150 abberations to about 10, which is acceptable.
The swabs are at least good and made recovery work, the solution is OK in that it does work to a point and it dried nicely on the first pass, however, tyring to get rid of more of what was still left, it made the situation 50x worse before I made my own solution to the problem.
Not a place you want to be in with a £2000 camera body.
So, four swabs for £15.99, good value? I don't think so.
If you suspect you have any oil or bio-matter(if you have ever blown into the body to remove something like a hair, water vapour will leave bio-splatter residue) on your filter look at an alternative solution (the solution/liqid they provide) to deal with it.
If you are sure its just dust then this "should" do the job.
