Hi Mehak, we're really sorry to hear you're not loving our Dish tabs. For best results, we recommend selecting the eco-cycle setting on your dishwasher. If you are using a shorter or cooler cycle, it sometimes works better to place the Dishwashing Tablet in the bottom of the machine rather than the dispenser.
We do also offer a 30 day guarantee though so if you'd prefer to return them for a refund please reach out to us at careau@koh.com - Team Koh
