Frequently Asked Questions
What actually causes tumblers to rust or discolor?
Rust and discoloration come from a combination of moisture, oxygen, and residues. Even stainless steel can show rust if paint chips expose lower-grade metal or if water and acidic drink residues sit in seams or under lids for long periods. Condensation (sweat) on the outside and trapped water in lid crevices are common culprits.
How can I clean my tumbler to prevent rust?
Wash all parts after use with warm soapy water, using a lid brush and straw brush for crevices. Rinse thoroughly and dry everything immediately — hand-dry the body and leave lids open to air-dry fully. For stubborn stains, a paste of baking soda and water or a 1:1 vinegar soak will lift residues; rinse and dry thoroughly afterwards.
Is dishwasher safe always fine for preventing rust?
Not always. Many lids are dishwasher-safe, but manufacturers often recommend hand-washing insulated bodies to protect powder coats and seals. Dishwasher detergents and high heat can accelerate paint chipping or degrade seals, which increases the risk of exposed metal and rust over time.
