Does lab go bad?

All KNF solutions can go bad this is why its taught ( The nose knows! ) if it smells bad then it has gone bad …LAB  has one of the shortest shelf life’s in KNF its only recommended to store it for about 1 year if not refrigerated …i make LAB a few times a season cause its so simple to make ..i try not to make too much and try to use whatever’s left over in the house over the winter to clean or take some LAB baths ( great for your skin and helps healing minor skin wounds ) i probably use LAB just as much for personal use as i do out in the garden
