- Discoloration: Changes in color may indicate oxidation or bacterial growth.
- Unpleasant odor: A sour or rancid smell is a sign of spoilage.

How to Extend the Shelf Life of Bar Soap
To maximize the lifespan of your bar soap, follow these tips:
- Keep it dry: Store soap in a well-ventilated area to prevent moisture buildup.
- Avoid exposure to heat and sunlight: Keep soap away from direct sunlight and heat sources.
- Use a soap dish: Place soap on a soap dish with drainage holes to prevent water from accumulating.
- Wrap unused soap: Unwrapped soap can oxidize, so wrap unused bars in plastic or paper.
When to Discard Bar Soap
If you notice any signs of spoilage, such as discoloration, odor, or mold growth, discard the soap immediately. It’s also advisable to replace bar soap every 6-12 months, even if it shows no signs of spoilage.
Safety Precautions
Using spoiled bar soap can lead to skin irritation, infections, or allergic reactions. Always inspect soap before use and discard any questionable bars.
Special Considerations for Antibacterial Soap
