Can I mix and store Re-Lyte in a metal container?

Most metallic drink containers are designed to resist corrosion caused by the combination of water and electrolytes.

Yes, you can store Re-Lyte in some metal containers, but there are metal containers you’ll want to avoid. Let’s talk about how electrolytes interact with metals so you can make an informed decision when selecting a container. 

Electrolytes, when combined with water or moisture, will cause some metals to exchange electrons with the electrolyte solution. This ionic exchange can cause oxidization and corrosion–think rust or green copper patina. 

Luckily, most metallic drink containers are specifically engineered to be corrosion-resistant. This technology is similar to bio-safe metals that are used in medicine (bone pins, knees, hips, etc.). Our bodies are literally saline (salt water) in motion, so it’s important to use properly designed metal in the body that doesn’t corrode. Similarly, using a drink container made from properly designed metal not only safeguards the container but also ensures that no unwanted odd colors, odors, or metals mix with your Re-Lyte. 

So what type of metal drink container is considered safe for an electrolyte drink?  We recommend looking for either stainless steel or stainless steel-lined drink containers. If you want to be extra cautious, look for containers made of 316 stainless steel, which is known for its exceptional salt resistance. 

If you want to avoid metal altogether, there are also some really neat glass-lined water bottles that might be more your style. Just keep in mind that you’d never want to store hydrated Re-Lyte, or any salt solution, in a cast iron or mild-steel container as those are very susceptible to corrosion in the presence of salt, water, and air.
