Why
The OXO Good Grips measuring cup is made of Tritan copolyester (body) and silicone (gasket) with printed measurement markings. Tritan is dishwasher-safe up to 212°F, but the high heat and alkaline detergent can cause the silicone gasket to degrade over time (hardening, cracking, loss of seal). The printed markings may fade or peel after repeated dishwasher cycles. OXO officially states the cup is top-rack dishwasher safe, but recommends hand washing the lid and gasket to extend life. The lid has a snap-fit seal that can warp in high heat, compromising the pour spout seal. The handle is part of the Tritan body and is safe. Failure modes: gasket seal degradation, marking fading, lid warping.
How do you wash OXO measuring cup?
- Disassemble the lid by pulling out the silicone gasket.
- Hand wash the gasket with mild soap and warm water, then air dry.
- Wash the Tritan body and lid frame on the top rack of the dishwasher, away from the heating element.
- Use a gentle cycle with low heat and avoid high-temperature drying.
- Remove promptly after cycle and air dry completely before reassembling.
- Reinsert the gasket only when both parts are fully dry.
What happens if you put OXO measuring cup in the dishwasher?
If you put the entire OXO measuring cup in the dishwasher, after one wash you may not notice any change. After repeated washes (10+), the silicone gasket will likely become stiff, lose its flexibility, and may crack, causing leaks around the lid. The printed measurement markings may start to fade or peel, especially if the cup touches the heating element. The Tritan body itself will remain clear and unclouded, but the lid's snap-fit may warp slightly, making it harder to seal. The damage is primarily cosmetic (markings) and functional (gasket seal). The cup will still measure accurately, but the lid may no longer pour cleanly. Over time, the gasket may need replacement.
Frequently asked questions
- What water temperature can the OXO measuring cup withstand?
- The Tritan body can withstand temperatures up to 212°F (boiling water), but the silicone gasket is rated to about 400°F. However, prolonged exposure to dishwasher heat cycles can degrade the gasket.
- Will the printed markings peel over time?
- Yes, the markings are printed on the Tritan surface and can fade or peel with repeated dishwasher use, especially if the cup contacts the heating element or abrasive detergents.
- Can the OXO measuring cup go in the microwave or freezer?
- The Tritan body is microwave-safe for short reheating (without lid) and freezer-safe, but avoid sudden temperature changes to prevent stress cracking.
