On Sunday I bottled an all grain batch and after sterilising the bottles in a bucket of VWP solution and rinsing out the FV I poured the used VWP solution into the FV. Can I just leave it in there and drain and rinse the FV this weekend and use it or will it no longer be sterile? If not would just topping up the VWP a bit (another tsp in 25l) be enough or should I just forget it and resterilise?
