Yes, dishwashing liquid can expire, although it typically remains effective for a long time. Most brands of dishwashing liquid do not have a specific expiration date printed on the bottle. However, over time, the formula can degrade, affecting its cleaning power. This decline is usually gradual, and you may only notice it when the liquid seems less effective at cutting through grease or creating suds. While using expired dishwashing liquid isn’t harmful, you might not get the same cleaning efficiency, making it worth replacing after its effectiveness has diminished.
- How long does dishwashing liquid last? Generally, dishwashing liquid can maintain its effectiveness for about 12-18 months after opening.(1) After this period, its ingredients may start to separate, change colour, or develop an unusual odour. These are clear signs that the product has aged and is no longer performing at its best.
- Does dishwashing liquid have an expiration date? While manufacturers rarely list an exact expiration date, many recommend using the product within two years of manufacture for optimal results. To extend its shelf life, store your dishwashing liquid in a cool, dry place, away from direct sunlight.
