I read somewhere that you can use bleach and vinegar together in small enough amounts that you don't need to rinse. However it didn't say in what amounts. Has anyone tried this or know what the correct dilution level would be. I normally use Brewshield from my LHBS but it's expensive and goes quickly. I'd prefer to use stuff I can easily buy from the supermarket but not have to rinse since I don't like to use heaps of water
