No, it is not recommended to put ceramic planter pots in the dishwasher. Dishwashers are designed for cleaning dishes, glassware, and utensils, and they may not be suitable for cleaning ceramic pots.
Ceramic planters can be porous, and the high temperatures and harsh detergents used in dishwashers can potentially damage or discolor the glaze or finish of the pot. The dishwasher's intense water jets and tumbling action may also cause the pots to chip or crack, especially if they have delicate or intricate designs.
Instead, it is best to clean ceramic planter pots by hand using a mild detergent, warm water, and a soft brush or sponge. Gently scrub the pot's surface to remove any dirt or residue. Rinse thoroughly and allow the pot to air dry before using it again.
