Regular, white paste toothpaste. Wipe it on and let sit for a couple min, and wipe it off.
Anti-fog coatings are applied to the inside surface of the astronaut's helmet visor to prevent fogging. Additionally, proper ventilation and air circulation inside the helmet help reduce humidity and condensation buildup. Astronauts may also use anti-fog wipes or solutions as needed during a spacewalk.
The four types of fog are radiation fog, advection fog, upslope fog, and evaporation fog. Radiation fog forms on cool, clear nights when the ground loses heat rapidly. Advection fog occurs when warm, moist air moves over a cold surface. Upslope fog is formed when moist air is forced to rise up a slope or mountain. Evaporation fog occurs when air near the surface is cooled to its dew point by evaporation.
Steam fog is fog that that comes off of water. It comes up when it is really ht outside.
The fog that results from the nightly cooling of the earth is called radiation fog. It forms when the ground cools rapidly, causing the air near the surface to cool and reach its dew point, leading to condensation and fog formation.

It is not normal for a military gas mask to fog up.

To prevent glasses from fogging up in cold weather, try using anti-fog wipes or sprays, adjusting the fit of your glasses to allow for better airflow, or wearing a mask that directs your breath downward.

I believe what your talking about is a respirator.
It is recommended that a SCBA face piece is washed after every use. When not in use, it should be cleaned every couple of weeks.
Technically, it might be compatible. However it would be illegal in the United States to use it with anything but a Scott SCBA system. Scott SCBA systems would not have been submitted to NIOSH for approval with MSA bottles.

Features that prevent the binoculars from being damaged by water and internal fogging. Waterproof binoculars are sealed to prevent water ingress, while fog-proof binoculars have internal gas (such as nitrogen) to prevent condensation.
There are no fog-proof lenses available. I assume plastic lenses might be slightly less likely due to fog compared to glass, considering that plastic is much less thermally conductive. However, I have heard that plastic lenses still fog up. The colder the water is, the more likely it is that water will condense on the inside of the lens. The best way to prevent fogging is to apply spit or a commercially available anti-fog agent to the inside of the mask lens and rinsing just prior to diving. I dive in cold water (50f) all the time and don't have problems with fogging when I use anti-fog.
