Tank Cloth Diaper and Insert Features Layers and Materials

  1. Before washing, make sure any solid matter is removed from your product. For items with heavy soiling that may stain or develop odors, rinse under cold running water until the water runs clear before storing for wash day.
  2. For a deep clean, start with a pre-wash on a short cycle using warm water (up to 140°F / 60°C) and the recommended amount of detergent, such as Tide Original to Line 1. Follow with a heavy-duty, longest-cycle wash in warm or cold water, again using the appropriate detergent amount. To ensure proper agitation, add other items to create a full load.
  3. For everyday or lighter messes or items already pre-rinsed, a regular cycle in cold or warm water (up to 140°F / 60°C) with the normal amount of detergent is sufficient.
  4. Whenever possible, hang to dry. If you’re in a rush, you can tumble dry on low.

  • Make sure any solid “stuff” is already out of the diapers, inserts, and liners before you throw them in the washer.
  • Be sure to unsnap the inserts from the diaper cover and each other before washing.
  • Pre-wash the diapers (short cycle) in warm water using the recommended brand and amount of detergent. We recommend Tide Original to Line 1.
  • Heavy Duty (longest cycle) warm/cold wash with proper detergent amount. We recommend Tide Original, amount depends on size of load.
  • Hang to dry as often as you can, tumble dry low if you are in a rush!

Work well

I love these inserts they work well

Good when using both but bulky

Despite marketing by Uncle Mo saying that babies younger than 3 months only need the small insert, we had constant leaks by 1 month old I think when we did that. You really need both for adequate absorption, but it's really quite bulky.

Hey there, Jaye! Thank you so very much for taking the time to review your Tank Cloth Diaper! Some babies are as leaky as they are cute and for those 'heavy wetters', our Delight Team is here to help with a fit consultation any time that you need! We can be reached at delight@lilhelper.ca. Did you know that we also have a parenting group on FB? Check out 'Lil Helper Unsnapped: Parenting Tips & Advice' to connect with other parents, ask fit questions, share product ideas, and catch the latest scoop from Lil Helper about new product releases and restocks!

They absorb very well and are easy to clean. They keep baby dry in between changes. Love the cute prints on the bigger part of the insert! Thank you for these! :)
