Why
The BrüMate Tumbler body is made of 18/8 stainless steel, which is resistant to dishwasher heat and alkaline detergent, but prolonged exposure can cause minor oxidation or water spotting. The lid is Tritan plastic, which may warp or become cloudy under high heat (especially on bottom rack). The silicone gasket can degrade over time, losing its seal. The manufacturer recommends hand washing the lid and gasket to preserve the vacuum seal and decals. Repeated machine washing of the lid can cause decal peeling and gasket failure, leading to leaks. The body is generally safe on the top rack, but hand washing is preferred for longevity.
How do you wash BrüMate Tumbler?
- Disassemble the lid by twisting off the top and removing the silicone gasket.
- Hand wash the lid and gasket in warm soapy water using a soft sponge.
- Rinse thoroughly to remove all soap residue.
- Wash the stainless steel body with a soft sponge and mild detergent; avoid abrasive pads.
- Rinse the body and dry immediately with a soft cloth to prevent water spots.
- Reassemble the lid only after all parts are completely dry.
- Store with the lid off to allow airflow and prevent odors.
What happens if you put BrüMate Tumbler in the dishwasher?
If you put the entire BrüMate Tumbler in the dishwasher, after one wash you may notice water spots on the stainless steel body and slight clouding on the Tritan lid. The silicone gasket may swell temporarily but usually returns to shape. After repeated washes, the lid's decals will begin to peel or fade, and the gasket may lose its elasticity, causing leaks. The stainless steel body may develop minor pitting or oxidation if the dishwasher's rinse aid is low. The damage is primarily cosmetic for the body but functional for the lid and gasket, as a compromised seal reduces insulation performance. Over time, the lid may warp, making it difficult to screw on properly.
Frequently asked questions
- Can I put the BrüMate Tumbler in the microwave?
- No, the stainless steel body is not microwave safe. The metal can cause sparks and damage the microwave. The lid is also not microwave safe due to the plastic and silicone components.
- Is the BrüMate Tumbler freezer safe?
- Yes, the stainless steel body can be placed in the freezer for short periods to chill drinks. However, avoid freezing the lid as the silicone gasket may become brittle and crack.
- How often should I replace the silicone gasket?
- The gasket should be replaced every 6-12 months depending on use. Signs of wear include cracking, stretching, or loss of elasticity, which can cause leaks.
- Can I use bleach or abrasive cleaners on the tumbler?
- No, avoid bleach and abrasive cleaners as they can damage the stainless steel finish and degrade the silicone gasket. Use mild dish soap and a soft sponge instead.
