Is Glasslock Containers dishwasher safe?
Sometimes — with care
Glasslock containers are generally dishwasher safe, but hand washing is recommended to preserve the lid seal and clarity.
Why
The glass base is heat-resistant and dishwasher safe, but the plastic lids may warp or degrade over time in high heat. Many manufacturers recommend placing lids on the top rack or hand washing to extend their life.
How to wash it
Wash glass bases on the top rack of the dishwasher or by hand. Hand wash lids with mild soap and dry thoroughly to maintain the seal.
