Vixen ascot not water proof?

[leehai1980]

I rinse the objective lens with water tap and I saw some liquid like substance in the binocular . I tot this binocular is waterproof and nitrogen filled .

Oooh you should never rinse optics under running water..

They are supposed to be nitrogen filled and "waterproof" but as with all sealed optics, seals and O-rings can leak over time or from other damage (e.g. solvents) or even manufacturing defects, it's best to never test their water resistance, ever.

You might have to send the binoculars to be professionally cleaned if there are any water stains or residue stains on the inside of the lenses.

Cotton swabs and diluted Isopropyl Alcohol is what I use...

Sometimes we need to take the 'Waterproof' concept with a 'pinch of Salt'. Normally it never is 100% waterproof on most everything. Also,..letting water run all over it may have caused some to seep in due to pressure or small gaps. Even if it doesn't,...small gaps trap the moisture and leave residue causing streaks here and there.

Is the liquid like substance on the lens? Some lenses have this 'black gunk' that they use to hold the objective in place. I had a similar prob with one of my EP's when I put too much cleaning solution on it. Streaks appeared and when I dismantled the whole EP,...there was this 'gunk' which when wet, streaks onto the lens. Eventually I cleaned all the gunk out and that helped.

But yeah as Fuzzy mentioned,...never rinse. Even the whole body under running water. Some cleaning solution or warm soapy water and a rag is good enough to clean the exterior. Concentrated cleaning on spots that are dirty rather than bathing it.

Only things that I have seen that are waterproof are the boxes used to house camera's and DSLR's for scuba diving use!! Expensive but can withstand depths to 40 feet!! Used one before and camera is Bone dry!! But if the sealing rubber is damaged or softened...the pressure from 40feet will seep in easily!
