Nellie's Dish Butter: a semi-solid, zero-waste alternative to liquid dish soap. A little goes a long way, so you don't need much. Wet a Forever Brush, dishcloth or sponge, gently dab the Dish Butter - and wash away! Tip and drain any excess liquid from your Dish Butter container (over the last few dishes) before drying it out. When it's time to refill your Dish Butter container, simply remove 1x Dish Butter Refill and push it gently into the container.
