Slow Cooker Insert in the Dishwasher? An Expert Weighs the Safety Factors

Check the Manufacturer’s Guidance
Dishwasher safety varies among removable stoneware inserts, according to Noah Pinsonnault, a reviews analyst in the Good Housekeeping Institute’s Home Care & Cleaning Lab. He recommends consulting the owner’s manual instead of assuming an insert is dishwasher-safe.
Let the Insert Cool
Allow the insert to cool completely before washing it. Pinsonnault warns that a sudden temperature change can crack some materials, so avoid putting cold water on a hot insert.
Clean Without Scratching
Use a nonabrasive sponge or a nylon brush to loosen residue without scratching the surface. Soaking can also help release baked-on messes before you finish cleaning at the sink or in the dishwasher.
Key points
- Dishwasher safety depends on the insert’s manufacturer and model.
- Check the owner’s manual before placing an insert in the dishwasher.
- Let the insert cool completely and avoid cold water on a hot surface.
- A nonabrasive sponge, nylon brush or soaking can loosen residue.
