Hi,

Typically the biocleaner does not have an expiry but once you expose it to air the content will biodegrade slowly and depends to its exposure to air. Unopen bottle can last for around 2-3 years. If you have started using and open the cap, you should use it within 1 year for better performance. The cleaning performance will drop when it ages.

Thanks.
