how to know if soap is expired

If you’re wondering if your soap is expired, there are a few ways to know for sure. One way is to visually check the expiration date printed on the soap. If it’s past the date, the soap is likely expired. Another way to tell is by using a soap testing kit. These kits can usually be found at pharmacies or online. Once you have the kit, you can test the soap for signs of spoilage, like mold or yeast. If any of the tests come back positive, the soap is likely expired and should be thrown away.
