Anti-fog Spray FAQs

There are many different kinds of anti-fog spray. There are many different uses for anti-fog spray. So, of course, there are many different questions that come up about it as well regarding anti-fog spray. These are some of the most frequently asked questions about anti-fog spray.

What does anti-fog spray do?

An anti-fog spray is used to create a hydrophobic coating on the surface of your glasses, goggles, or many other items. This coating creates a surface that repels water droplets so it will not fog up.

Will the same anti-fog spray work on different items?

Many sprays will prevent fogging on a variety of surfaces. For example, KleerVu anti-fog cleaner is designed to prevent fogging on everything from eyeglasses to binoculars, to helmet visors, and many more.

Is there extra work required when you use anti-fog spray?

As with any of your possessions, you’ll want to take proper care of them so they stay in good shape. Using anti-fog spray is an example of how you can care for many of your belongings. But the spray doesn’t mean you need to do anything else special. Just take care of them the same way you normally would.

How long will a small bottle last?

A small bottle could last anywhere from a few days to years, depending on how often you use the anti-fog spray. The better question to ask is how many applications you will get out of each bottle. An 8 oz. bottle of KleerVu will give you more than 1,000 applications when used as directed!

My anti-fog spray has worked before but not anymore. Why?

This can happen for a couple of reasons. Your anti-fog spray may be low-quality. It also may have reached its expiration date. The other reason may be that the surface of your glasses or goggles, etc may have been mistreated. For example, if a surface is rubbed too much, the anti-fog coating can wear off.

Why does my anti-fog spray work sometimes and not others?

Some factors can make many of the anti-fog sprays ineffective (in addition to the reasons just mentioned). Poor conditions can make it nearly impossible for a spray to do its job. One example of this could be if you are swimming in hot water. Not much a spray can do about fogging in that environment. How can I ensure getting the best results?

One of the best anti-fogs to choose is KleerVu because of this anti-fog guarantee

“Our KleerVu Anti-Fog Guarantee promises that our cleaner will counteract fog when used as directed, and applied regularly as needed. The frequency of KleerVu application will be dependent on the amount of physical activity exerted and the weather conditions and will vary. There are some lenses that will not anti-fog with KleerVu, or any other type of cleaner. These excluded lenses include Crizol, anti-reflective lenses, Teflon lenses, and other types of lenses with special coatings. For these special types of lenses, we have developed Pristine Lens Cleaner. Pristine is not an anti-fog formulation, and is not guaranteed to counteract fog.”
