Mask Preparation

New masks require pre-treatment before you dive with them. Masks leave the factory with an invisible protective film coating the tempered-glass lenses. Left untreated, a mask is prone to fogging, condensation due to water vapor, and microscopic water droplets on the inside. Fogging will reduce your visibility, as well as compromise your comfort and safety if you can’t see properly underwater.

Sea Buff

Gear Aid Sea Buff is required on new masks to carefully remove silicone film residue left on the inside lenses of new dive mask lenses by the manufacturing process and prepares the surface for the first application of Sea Drops™ 

Specially formulated dive mask pre-cleaner and slate cleaner. Sea Buff carefully removes residue left on new dive mask lenses by the manufacturing process. Sea Buff is a specially formulated dive mask pre-cleaner and also a very effective diving slate cleaner.



Take a thimble-sized amount of toothpaste and rub it on both sides of the dry lens. Give it a good circular rub. Make sure your hands are clean.

Rinse the lens while rubbing away the toothpaste. Note that toothpaste may accumulate in the edges, so use a little more water pressure if needed to remove it, or you may use a soft, wet and clean washcloth.

Once the toothpaste is rinsed away, dry the lens with a clean towel or rag.

Repeat these steps, drying the lens in between each application, 5 to 7 times


A method that is 'hot-ly' contested in the diving world

Many divers are adamant that using fire to burn the silicone coating off the lenses is the most effective way to pre-treat your mask. It is sometimes controversial as, unsurprisingly, taking a naked flame from a cigarette lighter to your shiny new mask may seem counter-intuitive. However, when done correctly, it can be very effective.
