Why
The Brumate mug body is made of double-wall vacuum-insulated 18/8 stainless steel, which is dishwasher safe under high heat and alkaline detergent; however, the lid contains plastic components and a silicone gasket that can degrade over time. The specific failure modes for the lid include seal degradation (silicone can swell or lose elasticity) and potential warping of plastic parts, leading to leaks. The manufacturer, Brumate, recommends hand washing the lid and gasket to preserve the seal, while the stainless steel body can go on the top rack. Repeated dishwasher cycles can cause the silicone gasket to harden or crack, compromising insulation and leak resistance. The stainless steel body itself is durable and will not rust or warp, but the exterior powder coating may chip if knocked against other items.
How do you wash Brumate mug?
- Disassemble the lid by removing the silicone gasket and any sliding mechanism.
- Hand wash the lid, gasket, and sliding parts in warm soapy water using a soft sponge.
- Rinse thoroughly to remove all soap residue.
- For the stainless steel body, place it on the top rack of the dishwasher, away from heating elements.
- Use a gentle cycle with low heat and avoid harsh detergents.
- After washing, air dry all parts completely before reassembling.
- Reassemble the lid, ensuring the gasket is seated properly.
What happens if you put Brumate mug in the dishwasher?
If you put the entire Brumate mug in the dishwasher, after one wash you may not notice immediate damage, but the silicone gasket can absorb detergent and start to swell or lose its shape, leading to a less secure seal. After repeated washes (5-10 cycles), the gasket may become brittle or crack, causing the lid to leak. The plastic components of the lid can also warp from high heat, making the sliding mechanism stiff or misaligned. The stainless steel body will remain intact, but the exterior powder coating may develop small chips if it contacts other dishes. The damage is primarily functional (leaking lid) rather than cosmetic, and the mug will still insulate, but the lid may need replacement.
Frequently asked questions
- Can I put the Brumate mug in the microwave?
- No, the stainless steel body is not microwave safe, and the plastic lid may warp or melt. Always transfer contents to a microwave-safe container.
- Will the powder coating on the mug chip over time?
- Yes, the powder coating can chip if the mug is knocked against hard surfaces or other items in the dishwasher. Hand washing the body reduces this risk.
- How often should I replace the silicone gasket?
- Replace the gasket every 6-12 months or sooner if you notice any cracking, hardening, or loss of elasticity to maintain a leak-proof seal.
- Can I freeze my Brumate mug?
- Yes, the stainless steel body is freezer safe, but avoid freezing the lid as the plastic and silicone may become brittle. Leave room for liquid expansion.
