Rescue™ Concentrate and Rescue™ Ready-to-Use are two separate formulations. Both are based on the same patented Accelerated Hydrogen Peroxide® technology, however they are completely different products.
Although the technology behind all Rescue™ disinfectant products is the same, the Ready to Use liquid and Concentrate are actually two distinct formulations and are not to be confused as the same product: the Concentrate is designed to be diluted before use, and the Ready-to-Use formulation is available in liquid form and as wipes which should not be diluted.
The Ready-to-Use products have a shorter contact time (1 minute), while the Concentrate requires a contact time of 5 minutes. You cannot dilute the Concentrate product to have a shorter than 5 minute contact time.
The Ready-to-Use products have a shelf life of 3 years (stored in a sealed canister to prevent exposure to air and to keep it fresh), and the Concentrate has a shelf life of 3 years, or 90 days once diluted.
