How to Use Epsom Salt in a Jet Tub

Epsom salt can ease muscle pain, reduce inflammation and flush toxins from your system. When combined with the therapeutic properties of a jet tub, Epsom salt are the perfect remedy for a sore or stressed body. Although it's safe to use Epsom salt in your jet tub, you'll need to take precautions to ensure that residue from the salt doesn't harden inside your whirlpool jet system.
