Learn how to apply Cat Crap lens cleaner and anti-fog treatment to your dog's goggles for clear vision in cold or humid weather, plus common mistakes to avoid.

Quick answer

Apply a small amount of Cat Crap lens cleaner to each lens, rub it in with a clean finger, then buff it off with a soft cloth. This restores clarity and adds an anti-fog layer that helps in cold weather or humid conditions.

Why Cat Crap works on Rex Specs lenses

Cat Crap is formulated to be safe on all Rex Specs lenses, so you can use it without worrying about damaging the coating. It works as both a cleaner and an anti-fog treatment, which makes it a practical choice for dog goggles that see a lot of wear.

Unlike some household cleaners, Cat Crap is designed for optical surfaces. That means it lifts dirt and smudges without leaving a residue that could attract more dust or interfere with your dog's vision.

When to use it (and when not to)

Use Cat Crap whenever your dog's lenses look smudged or when you notice fogging during walks. It's especially useful in cold weather, where temperature changes can cause condensation, and in warm, humid climates where moisture builds up quickly.

One important limitation: Cat Crap cannot be shipped when the temperature is below freezing. If you're ordering in winter, plan ahead or check the weather before placing your order. Also, avoid using Cat Crap on any non-Rex Specs lenses unless the manufacturer confirms it's safe.

How to apply Cat Crap to dog goggle lenses

Remove loose dirt first: Wipe the lenses with a dry, soft cloth to remove dust or grit. This prevents scratching the lens when you rub in the cleaner. Checkpoint: if you feel grit, rinse the lens with water and dry it before applying Cat Crap.
Apply a small amount of Cat Crap: Squeeze a pea-sized amount onto your fingertip or directly onto the lens. Remember that a little goes a long way. Common mistake: using too much product, which can leave a hazy film that's hard to buff off.
Rub it in gently: Use your fingertip to spread the product evenly across the entire lens surface, including the edges. Avoid pressing hard. Checkpoint: make sure you cover the whole lens, not just the center.
Buff it off with a clean cloth: Use a dry, lint-free cloth to buff the lens until it's clear and dry. Turn the cloth to a clean section as you go. Common mistake: using a dirty cloth, which can reintroduce smudges or leave lint behind.
Check for streaks and repeat if needed: Hold the lens up to the light. If you see streaks or haze, apply a tiny bit more Cat Crap and buff again with a fresh cloth. Checkpoint: the lens should be completely clear with no visible residue before you put the goggles back on your dog.
