Perhaps you could negotiate? Hold all those lovely clean, shiny jars just out of reach and say "If you will only discard all your festering jars, filled with sludgey turps and stiff brushes, then all these treasures could be yours, to fill with a myriad of other treasures! Just think, my darling of entering the sanctuary that is your shed, and every possible screw, or nut or bolt that you heart may desire is there, waiting for you, categorised, labelled and....accessible! You could tenderly unscrew the jar from it's lid that is fixed to the underside of the shelf, yes yes, my darling, for that is where they will be, just hanging like ripe, glass fruits, ready for plucking, you would cup it gently in your hands, savouring the moment when you place it on your workbench and your eager fingers move gently inside to extricate that 6mm washer that you know that you need so badly"
Or something along those lines, anyway.........
