What Is Etching?
Etching is a permanent, hazy or cloudy condition that can develop on glassware, making it impossible to restore the original luster. This happens when metal ions are removed from the surface of the glass, leaving a roughened, exposed silica layer.
The process of etching is slow and can be caused or accelerated by several factors. While most glassware is made from a basic soda-lime glass, even water alone can cause etching over many dishwasher cycles.
How to Prevent Etching
Here's how you can help prevent or slow down the etching process, depending on your water type.
For Soft Water
Soft water naturally promotes etching. To help prevent it, we recommend the following:
-
Use minimal detergent. One tablespoon is typically enough.
-
Avoid overloading your dishwasher to allow for maximum rinsing.
-
Use a rinsing agent like Jet-Dry to help water sheet off the glass during the final rinse.
-
Use the correct water temperature of 140°F to 150°F (60°C to 65°C).
For Hard Water
Hard water can cause mineral and food deposits to stick to glass, which can also lead to etching. To counter this, you may need to adjust your washing habits:
-
Increase detergent in small increments. Start with one teaspoon at a time to find the optimal amount for your dishes.
-
Use a rinsing agent like Jet-Dry to ensure water sheets off during the final rinse.
-
Use a product like Glass Magic in addition to your detergent. This helps strip away hard water film and food deposits that can cause damage.
