Is Oster Blender dishwasher safe?
Sometimes — with care
Oster blender jars are generally dishwasher safe, but lids and blade assemblies should be hand washed.
Why
The glass or plastic jar can typically go on the top rack of the dishwasher, but the lid and blade base contain seals and gaskets that may degrade with high heat and harsh detergents. Hand washing these parts extends their life.
How to wash it
Place the jar on the top rack of the dishwasher. Hand wash the lid, blade assembly, and any rubber gaskets with warm soapy water and dry thoroughly.
