Pura Stainless steel bottles can be safely washed in the dishwasher or by hand. Thanks to the wide neck of the bottle, this is very easy to do.
The bottles are very easy to disassemble and therefore care for them will not be difficult.
Most deposits from hard water, other deposits, or discoloration can be removed by soaking the bottle overnight in table vinegar.
Use a dishcloth to clean the bottles, but do not use anything like metal or steel wool as this can damage the protective oxide layer of the stainless steel.
Never use bleach or antibacterial agents. The simplest, most environmentally friendly and safest remedy is just baking soda and water.
