These organizers are easy to clean!
You can start with a wet paper towel or baby wipe to clean small smudges or debris.
If the above does not work you can submerse in dish soap and luke-warm water.
While some have had success with the FLEXIBLE items being top rack dishwasher safe, we suggest just soap and water for all of our items. DO NOT put the hard non-flexible items in the dishwasher as they will be warped.
