How to Store Epsom Salt to Keep Its Potency?
Epsom salt has a long shelf life and can be used for years without any issues. However, it's essential that you store it properly if you intend to reap all of its health benefits and uses.
Let's go over ways you can keep your Epsom salt from being contaminated and going bad.
Away From Moisture
When water touches a cup of Epsom salt, it's very likely that it'll dissolve, the same as other salts too.
Humidity is an enemy of Epsom salt, and it'll form a clump when exposed to moisture.
Water in any form is the major cause of spoiling salt. To prevent your magnesium sulphate from expiring, keep it in a dry place.
In any case, if you want to have an Epsom salt bath, there's no point taking your full container of Epsom salt into the bathroom. Use a spoon and take out a small portion and pour it into your bathtub. Mistakes happen, and you wouldn't want your entire Epsom salt to get dissolved in water probably because you missed a step.
Keep in Dark Places
Epsom salts degrade in quality when exposed to light. Ideally, it's advised that you store it in a box, and place it in a dark place. When you get to most grocery stores, you'll notice that Epsom salt is always in a dark container, and that's because they are trying to preserve it.
Epsom salt will lose its usefulness when you keep it under the sun for a long time, expired or not.
Free From Pests
Epsom salts can act as a source of repellent for insects; this means you can use it in getting rid of mosquitoes. To increase food production, Epsom salt is used in garden prepping, and also because it helps deter certain insects.
However, the bitter truth is that it doesn't keep rodents away, and if they come across it, they'll most likely have a fun day.
The best way to prevent this is to keep it in a rodent-proof container.
Keeping your Epsom salt away from water and sunlight is an easy way to prevent contamination.
Epsom salt has different grades, but at the end of the day, it'll only keep being beneficial if you store it well.
In conclusion, Epsom salt doesn't expire, and you can use it as a preservative as well.
When buying Epsom salt, go for the 100% natural option, as it meets food-grade standards, making it extremely safe to even use as a natural laxative. On that note, be careful not to ingest too much Epsom salt as it's still magnesium overdose and can cause diarrhea. If you feel the need to increase your magnesium levels, use supplements.
Luckily, unlike most products, Epsom salt expire only when mishandled.
