Just admit it… you haven’t cleaned your lenses in a while, have you? Let alone a good wet cleaning. I know, it’s easy to let it go and forget about it. So go do it now!!!
Here’s a little refresher course on wet cleaning your lens elements (and some product suggestions in case you don’t have the stuff already). Keeping your equipment clean is a important part of basic maintenance and it will make your gear last longer. Lenses are no exception, and it’s easy to forget about deep cleaning the front and rear elements because they usually appear to be quite clean at a glance. But if you haven’t given them a good wipe-down for a while, it’s more than likely that you’ve accumulated some dust and grime.
Here are the basic steps for wet cleaning your lens. If you’ve never done it before, make sure you’re comfortable with the process and you understand the risks involved. As for the products involved… we’re talking less than $40 and the only consumables are the cleaning solution and tissues which should last a year or more.
