Salvo tablets that did not dissolve in the filter pan
That was one of the sad ironies of WISK tablets. Just as the push began for HE machines, WISK tablets, which were a fine, low sudsing product, could not be used in dispensers, nor could they go into the drum because the minimal amounts of water used could not guarantee that the tablets would dissolve. So you paid for tablets that had to be mushed up in order to go into the dispenser of the machine. I did crumble those tablets though for just as long as I could buy them and was sad when WISK gave up on a non-liquid detergent.
