Is Glasslock Really Dishwasher Safe?
Yes, all Glasslock containers are designed to be dishwasher safe. The tempered glass bodies can withstand the high temperatures and water pressure of a standard dishwasher cycle without cracking or breaking. However, the plastic lids are a different story. While they are also dishwasher safe, they are more susceptible to heat distortion and staining over time. To maximize lid longevity, it’s best to place them on the top rack, away from the heating element. For the glass bases, the bottom rack is fine, but avoid overcrowding to prevent chipping.
One common concern is cloudiness. Glasslock glass is non-porous and resistant to etching, but hard water minerals or detergent residue can leave a film. To prevent this, use a rinse aid and avoid overloading detergent. If you notice cloudiness, a quick hand wash with white vinegar usually restores clarity.
- Place lids on the top rack to avoid heat damage.
- Use a rinse aid to prevent mineral deposits.
- Avoid overloading the dishwasher to reduce glass-to-glass contact.
Top Tips for Dishwasher Cleaning Glasslock
To keep your Glasslock containers looking pristine, follow these simple tips. First, always scrape off food residue before loading. While the dishwasher can handle most messes, large particles can redeposit on glass and cause spots. Second, use a gentle cycle with lower heat if your dishwasher has that option. High heat can warp lids over time. Third, let containers cool completely before handling. Tempered glass is strong, but sudden temperature changes (thermal shock) can cause breakage. Never put a hot Glasslock container directly into cold water or a cold dishwasher.
For stubborn stains like tomato sauce or turmeric, pre-soak with baking soda paste or a drop of dish soap. Avoid abrasive pads or steel wool, as they can scratch the glass. If you prefer hand washing, use a soft sponge and mild detergent. The Glasslock Oven Safe Square 6pc set and other sets come with easy-to-clean smooth surfaces that resist sticking.

Common Mistakes to Avoid
Even experienced users make mistakes. One common error is stacking glass containers inside the dishwasher. When stacked, water can’t reach all surfaces, leading to poor cleaning and potential scratching. Always place containers upside down or at an angle for proper drainage. Another mistake is using the sanitize or high-heat drying cycle. While the glass can handle it, the lids may warp or lose their seal. Instead, use air dry or low-heat drying.
Also, avoid washing Glasslock with cast iron or other heavy metal items that can bump and chip the glass. And never use the dishwasher for Glasslock products that are not labeled dishwasher safe, such as some older lids or decorative pieces. Always check the bottom of your container for the dishwasher safe symbol.
How to Remove Cloudiness and Stains
If your Glasslock containers develop a cloudy film, it’s usually due to hard water or detergent buildup. A simple solution is to soak them in a mixture of equal parts white vinegar and warm water for 15–20 minutes, then wash as usual. For stubborn stains, make a paste of baking soda and water, apply it to the stain, let it sit for 10 minutes, then scrub gently with a soft sponge. For oily residue, a drop of dish soap on a damp microfiber cloth works wonders.
For the Glasslock Handy Rectangle 7.5 cups or larger containers, you can also run a cycle with a cup of vinegar placed on the top rack to clean both the dishwasher and your glassware. Regular maintenance keeps your containers looking new and prevents odors.
- Use vinegar soak for hard water cloudiness.
- Baking soda paste for tough stains.
- Run a vinegar cycle to clean dishwasher and glass.
Caring for Glasslock Lids in the Dishwasher
The plastic lids are the most delicate part of your Glasslock set. To keep them fitting snugly, always place them on the top rack, away from the heating element. Avoid using the heated dry cycle, as prolonged heat can cause warping. If your lids become loose or don’t seal properly, it’s time to replace them. Glasslock sells replacement lids, or you can repurpose the glass base for storage without a lid.
To prevent odors, rinse lids immediately after storing strong-smelling foods like garlic or fish. If odors persist, soak lids in a baking soda solution overnight. Never microwave lids, even if they are labeled microwave safe, as they can warp. For the best care, consider hand washing lids occasionally, especially if you notice any wear.
- Always place lids on the top rack.
- Avoid heated drying cycles.
- Hand wash lids if they show signs of wear.
With these dishwasher care tips, your Glasslock containers will stay crystal clear, odor-free, and functional for years. Whether you’re using the Glasslock Oven Safe Rectangle 6pc set for daily lunches or the Glasslock Mixing Bowl 3.75qt for baking, proper washing habits make all the difference.
