Why the stainless steel body should be hand-washed
Owala recommends hand-washing the stainless steel cup with warm soapy water to protect the outer finish. Owala’s FAQ says the stainless steel cups are technically dishwasher safe, but it strongly recommends hand-washing them to keep the finish looking good.
How to put an Owala lid in the dishwasher
- Take the lid apart: straw out, gasket out with its pull tab.
- Place the lid on the top rack, facing down so water can drain from the spout.
- Put the straw in the silverware basket.
- Hand-wash the gasket, or put it in the utensil basket where it cannot slip out.
- Let all parts dry, then reassemble and check the gasket is seated.
Do not put the assembled lid in the dishwasher. The gasket seals water out, so a fully assembled lid will not get clean inside.
Does the dishwasher wear out the gasket?
Many owners report that repeated dishwasher cycles stiffen the gasket’s pull tab and can stop it from sitting flat, which then causes leaks. This is owner feedback, not an Owala statement, so treat it as a reason to check the gasket now and then, not a rule. If your lid starts to leak, see Why is my Owala leaking?
What not to do
- Do not microwave an Owala. Owala warns that heating a sealed bottle can build pressure and blow the lid open.
- Do not use bleach or abrasive cleaners.
- Do not rely on the dishwasher for a stainless steel body if you care about the finish, even though it is technically dishwasher safe.
