Can you put mason jars in the dishwasher?
Most plain mason jars are dishwasher safe. Put lids and bands where they will not fall, and hand wash if you are preparing for actual canning.
Updated June 10, 2026
Why
Plain tempered glass jars tolerate dishwashing, but metal lids and sealing compounds need care.
Caveats
- Follow canning-safe sterilizing instructions when preserving food.
- Do not dishwash rusty bands or single-use sealing lids for reuse.
- Avoid sudden temperature shock.

Are canning jars dishwasher safe?
Yes, plain glass canning jars are dishwasher safe for everyday cleaning. Wash bands and lids where they cannot fall through the rack, and retire rusty bands and used single-use sealing lids rather than dishwashing them for reuse.
Can you sanitize canning jars in the dishwasher?
A dishwasher with a sanitize cycle can clean and pre-heat jars before canning, but it does not replace boiling-water sterilizing when a tested canning recipe requires it. Follow the sterilizing steps in your canning recipe or local food-preservation guidance.
