[QUOTE="meddyliol, post: 517309, member: 31964"] I recently purchased one of the Hoya NDX400 ND filters. This after reading reports that although a good filter, the main problem was cleaning it, especially when drops of water get on it. As this filter is going to be used near water a lot for blurring waterfalls etc, this does seem to be a problem. I emailed Hoya and they answered quite quickly to say that 'Please clean with a lens cleaner in the same way as a lens. It's possible to use dehydrated alcohol. When a splash of water adhere to a filter, please wipe it off as soon as possible. I have a bottle of Baader Wonder Fluid and am not sure what's in it or whether or not it would damage the filter. Some reports suggest that the coating on the filter comes off during cleaning (I am not sure what they were using). I find this a little hard to believe with modern multi coatings. Has anyone had any experience with this type of filter, I am afraid to clean it just in case. Thanks and merry xmas to all Brian :confused: [/QUOTE]
