Cleaning Sand from Your Binoculars
Yes, sand is the mortal enemy of a good optic and it can damage an instrument or lens in an instant. If was getting into sand on a regular basis, I would think twice about takiking along an expensive instrument. If you have a choice, go with an IF (individual eyepiece focus) model or a model with internal focusing to minimize the possibility of sand working its way into moving parts. Center focus models with external focusing parts are especially vulnerable to sand.
For sand particles on a lens, I use a soft camel hair lens brush and ever so gently brush the sand particles away. Using a lens cloth is usually a bad idea. Any pressure on the sand particles will scratch a lens. If you use a cloth at all, it should only be after you are absolutely certain all sand has been removed.
For sand particles on the body, the brush is also the method I prefer. Some people claim that compressed air is a good idea, but I have heard stories of air blowing sand even further into a mechanism.
