How to preserve used soap?

Soap should be kept dry after use and should not be soaked in water to prolong the use times of handmade soap.

After each use, put it in a hydrophobic container, in a dry, ventilated and cool place, and do not let the sun shine directly, so as to avoid the rapid fading, discoloration and odor of soap due to high temperature, which can prolong the life of soap.

Soap that is not used for the time being should be drained, sealed with plastic wrap and put in the refrigerator for refrigeration. The shelf life depends on the preservation environment, generally one to two years.
