Fogging Solutions for Swimming Goggles

If you’ve ever taken a breath underwater and seen a white cloud cloud your view, you know how annoying fogged goggles can be. The good news? You can fix it with a few easy steps that cost almost nothing. Below we break down the most reliable tricks and why they work, so you can focus on your strokes, not on wiping lenses.

Why Goggles Fog and What to Do About It

Fog forms when warm, moist air from your face meets the cooler surface of the lens. The tiny droplets scatter light, turning a clear lens into a blurry mess. To stop this, you need to either keep the temperature equal on both sides or create a thin barrier that stops droplets from forming.

One of the quickest ways is a simple anti‑fog solution. A few drops of baby shampoo mixed with warm water spread a thin film that reduces surface tension. After you rinse, let the goggles air‑dry; the film stays on the lens and fights fog for weeks.

If you prefer a store‑bought option, look for sprays labeled “anti‑fog.” They work the same way, but make sure the product is safe for silicone or plastic lenses. Apply a small amount, rub it in, then rinse lightly.

Everyday Practices to Keep Lenses Clear

Even the best solution can wear off if you treat your goggles roughly. Here are habits that extend the anti‑fog effect:

• Rinse before each swim. A quick dip in lukewarm water removes salt or chlorine that can break down the coating.
• Avoid touching the inside of the lenses. Oils from your fingers create hotspots where fog gathers.
• Store them dry and cool. A damp pouch encourages mold and reduces the lifespan of anti‑fog treatments.
• Use a small amount of saliva. In a pinch, spit on the inner surface, spread it thin, then rinse. It’s a cheap, instant fix, though not as long‑lasting as shampoo or spray.

For competitive swimmers, a quick “pre‑dip” before the race can make a difference. Fill a bowl with warm water, submerge the goggles for a few seconds, then shake off excess. The warm water equalizes temperature, delaying fog for the first few laps.

Lastly, check your fit. Goggles that squeeze too tightly push warm air into the lenses, while a loose seal lets cold water flood in. Adjust the strap so the goggles sit snugly but comfortably. A proper seal reduces the temperature gap and cuts fog at the source.

With these tips—anti‑fog solution, careful handling, and the right fit—you’ll spend less time wiping and more time swimming. Give one method a try today and see how clear your next lap can be.
