It is generally not recommended to wash eyeglasses in the dishwasher. While the dishwasher may seem convenient for cleaning various items, eyeglasses require more delicate care. Here are a few reasons why it's best to avoid washing eyeglasses in the dishwasher:
High Heat: Dishwashers typically use high temperatures to clean and dry dishes. The heat can potentially damage the lenses or coatings of eyeglasses, causing them to warp, crack, or become discolored.
Harsh Detergents: Dishwasher detergents are formulated to remove tough food stains and grease from dishes. These detergents may contain chemicals that can be abrasive or harmful to the coatings or materials used in eyeglasses. They can cause damage, such as scratches or erosion, to the lenses or frames.
Mechanical Damage: The dishwasher's intense water jets and the movement of dishes during the washing cycle can create a risk of mechanical damage to eyeglasses. The lenses can get scratched or cracked if they come into contact with other dishes, cutlery, or the dishwasher's internal components.
To properly clean your eyeglasses, it is recommended to follow these guidelines:
Hand Washing: Clean your eyeglasses by hand using a mild dishwashing liquid or specialized eyeglass cleaner. Gently rub the lenses, frames, and nose pads with your fingers to remove any oils, dirt, or smudges.
Lukewarm Water: Use lukewarm water to rinse off the soap or cleaner. Avoid using hot water as it may damage the lenses or frames.
Soft Cloth: Dry the eyeglasses using a soft, lint-free cloth. Avoid using paper towels or tissues, as they can leave lint or scratch the lenses.
Proper Storage: Store your eyeglasses in a protective case when not in use to prevent scratches, dust, or accidental damage.
By following these guidelines, you can help ensure the longevity and condition of your eyeglasses without risking damage from dishwasher use or contact with other dishes.
