Is it okay to use the BISSELL Carpet Care Formula in my new BISSELL Upright Deep Cleaner? I have an older BISSELL canister-type cleaner and had this product left over. Can I still use it?

The shelf life of BISSELL Cleaning formulas depends on several factors. These factors include whether the foil seal is still intact, humidity in your area, temperature where the cleaning formula is kept, and what other products are nearby. Typical shelf life is 12 months when opened or 18 months unopened.
