Why
The Rubbermaid Brilliance Container is made of Tritan copolyester for the body, which is a BPA-free plastic that can withstand dishwasher heat up to about 100°C (212°F) without warping. However, the lid contains a silicone gasket and a polypropylene (PP) frame with a snap-lock mechanism. In the dishwasher, the high heat and alkaline detergent can cause the silicone gasket to degrade over time, losing its seal and leading to leaks. The PP lid may also warp or become brittle after repeated cycles, compromising the airtight seal. Rubbermaid officially states that the container body is top-rack dishwasher safe, but recommends hand washing the lid to preserve the gasket and locking tabs. The specific failure modes are seal degradation (gasket hardening/cracking) and lid warping, which are functional issues that can cause leaks and reduced freshness.
How do you wash Rubbermaid Brilliance Container?
- Disassemble the lid by removing the silicone gasket from the inner rim.
- Hand wash the lid and gasket with warm soapy water and a soft sponge; avoid abrasive scrubbers.
- Rinse thoroughly to remove all detergent residue.
- Wash the Tritan body on the top rack of the dishwasher, away from the heating element.
- Use a gentle cycle with low heat and no heated dry to minimize thermal stress.
- Air dry all parts completely before reassembling to prevent mold growth.
- Reinsert the gasket into the lid, ensuring it sits flat and snug.
What happens if you put Rubbermaid Brilliance Container in the dishwasher?
If you put the entire container (lid and body) in the dishwasher, after one wash you may not notice immediate damage. However, after repeated washes (10-20 cycles), the silicone gasket will start to harden and lose elasticity, causing the lid to no longer seal tightly. You might see the gasket become discolored or develop small cracks. The lid's snap-lock tabs may also warp slightly, making it harder to close or causing the lid to pop off. The Tritan body will remain clear and intact, but the lid's functional failure will lead to leaks and reduced food freshness. The damage is permanent and functional, requiring replacement of the lid or gasket. Cosmetic issues like clouding are unlikely on Tritan, but the lid's plastic may become brittle and crack over time.
Frequently asked questions
- Can the Rubbermaid Brilliance container go in the microwave?
- Yes, the Tritan body is microwave-safe without the lid. Remove the lid before microwaving to avoid pressure buildup and potential lid damage.
- What temperature can the container withstand?
- The Tritan body can handle temperatures from -20°F to 212°F (-29°C to 100°C). The lid and gasket have a lower tolerance, so avoid extreme heat.
- How often should I replace the gasket?
- Replace the gasket if you notice it is hardened, cracked, or no longer seals tightly. With hand washing, it may last 1-2 years; with dishwasher use, it may fail sooner.
