Yes, it is generally not recommended to put greasy dishes in the dishwasher. Here's why:
Ineffectiveness in Cleaning: Dishwashers are designed to clean dishes using hot water and detergent. When you put greasy dishes in the dishwasher, the hot water and detergent may struggle to break down and remove the grease effectively. This can lead to dishes not getting cleaned properly and coming out of the dishwasher still greasy.
Clogging and Damage: Grease and oils can build up in the dishwasher's drain and filter, leading to clogging and potential damage to the dishwasher over time. Excessive grease can also cause issues with the dishwasher's spray arm, affecting its ability to distribute water evenly.
Residue on Other Dishes: Grease from one dish can transfer to other dishes during the dishwasher cycle, leaving a film of oil on everything in the load.
Unpleasant Odors: Grease in the dishwasher can contribute to unpleasant odors, especially if it sits in the dishwasher between cycles.
To avoid these problems, it's best to remove excess grease from dishes before placing them in the dishwasher. You can do this by scraping off any leftover food particles and wiping away the grease with a paper towel or cloth. Additionally, if you have a lot of greasy dishes, it's a good idea to do a quick pre-rinse with hot water to remove as much grease as possible before loading them into the dishwasher.
By taking these precautions and avoiding putting extremely greasy items in the dishwasher, you can help maintain the efficiency and longevity of your dishwasher while ensuring your dishes come out clean and free from grease residues.
