When you're relying on portable toilets on your property, you need to be prepared for the hazard that is the freezing temperatures of winter. Before you find yourself with a frozen portable toilet, you should take steps to help deter freezing. If this is your first winter dealing with portable toilets, you may not know how to do this. Here are a few different ways that you can protect them from the deep freeze.

Rock Salt

Adding rock salt to the tanks will create a brine solution that will resist freezing. Brine solutions are effective as long as the temperatures don't drop below zero on a regular basis. You can add a half-pound or so of rock salt for each gallon of water in the tanks. Adding more per gallon will provide you with greater protection, so the colder it gets where you are, the more salt you'll want to use per gallon of water.

The main thing you should consider if you're choosing to use rock salt as your antifreeze solution is that the brine mixture can cause steel to corrode. As a result, it's best to avoid using any kind of brine solution unless the tanks are aluminum or stainless steel.

Magnesium Chloride

Magnesium chloride works much in the same way as rock salt. In fact, you can even buy it in crystal form, like you do rock salt. However, magnesium chloride is also available in a liquid solution. One of the benefits of magnesium chloride is that it provides greater protection at lower concentrations. That means you'll be able to use less of the solution to keep the tanks from freezing. In addition, magnesium chloride protects in colder temperatures, so if the temperatures drop below zero, you'll still have protection. This can save you money and hassle.

Methanol

Methanol is another great way to keep your portable toilet tanks from freezing. Methanol doesn't require dissolving, so it's quicker to use. You just pour it in, making it a simpler choice. Another advantage to using methanol is that it isn't corrosive. That means you can use it in a portable toilet that has a steel tank without worry of damage or leaks. The downside is that methanol can be a bit more expensive than other options. In addition, you need to follow the recommended ratio for the mixture because an excessive concentration of methanol can make the tank flammable.
