the inside of the underwater casing discolored. It used to be a clear see-thru case but now, it has this white colored substance on the inside that makes it hard to see the display of the camera. I don't know what caused it. I wasn't able to use it for a long time and when i did used it on a swimming trip, after i've rinsed it and left it over night, the next day the discoloration appeared. I thought that it might have been caused by salt deposit so i soaked the inside of the casing with water and left it over night. The next day, it got worst. So took it out, tried washing it with soap and dishwashing soap, didn't work. I tried rubbing it with clothe, it cleared a little bit, but still there. I'll take a picture of it and post it here so that you'll have a visual of what i'm talking about, the white substance in the casing.
