Help, My Diapers Are Leaking!-Part 2

There are many reasons why cloth diapers can leak but usually there is a simple solution to fix the problem. Last week we discussed four possible scenarios why cloth diapers can leak. To view reasons 1-4 please visit the previous post here. Here are some more reasons and solutions: 5 ) Using the wrong detergent can lead to build-up and can make your diapers repel. Due to factors such as water mineral content and alkalinity, what can work for some will not work for others. Homemade detergents, excessive amounts of detergent, or hard water can affect absorbency. Please read our Care and Use:  info for complete washing instructions. Solution: Change detergent. 6 ) Fabric softeners and diaper rash ointment can coat the fibers of your diapers and make them leak. Solution: Strip your diapers by using Dawn dish soap and a small scrub bush with hot water in the sink or bathtub. (Do not use Dawn dish soap in the washing machine as it may void your warranty.) (Some products like lanolin or petroleum jelly (Petrolatum) are very hard if not impossible to get out.) 7 ) The diaper does not meet the absorbency needs of your baby. Solution: In this case, consider adding a cotton doubler or hemp insert to every change. 8 ) The waterproof lamination on your diaper or cover needs to be resealed. If you feel that the liquid is coming through the fabric, examine the lamination for cracks, holes or peeling. If this is the case, please refer to our replacement warranty at: Lamination defects are very rare, but lamination can crack or begin to peel with age and use, or if harsh chemicals are used routinely. Solution: An occasional 15 minute tumble in the dryer on high is actually beneficial to the waterproofing layer. This may reseal tiny pin holes in the lamination.

  • Hello Monica,

    I am sorry to hear that and I am happy to help. You can test your lamination to see if it is no longer working by laying a damp wash cloth inside a clean dry cover and allowing it to sit for a few minutes. Then examine the outer fabric for dampness.

    Do you normally dry on High when drying the Wraps? If so, they may have reached their lifespan, as drying on High can wear the PUL out quicker. We recommend to line dry as often as possible, or dry on low and remove them as soon as they are dry.

    Stash size is another factor in lifespan, as a larger stash will see less wear and tear. Smaller stashes do work for many families, but they will show signs of wear sooner, as well. Detergent, washing routines, and water types can also factor into lifespan, as well. If you have any questions, I am happy to talk with you, just email me at

  • Help! I got a new fluffy mail shipment and opened them up. I prepped the inserts hemp and mf separately and then washed the covers. My problem is the first time wearing them my 10 month old leaked through the PUL. What’s wrong? This is the 4th baby I’ve cloth diapers. What would make a NEW diaper leak when properly prepped?

  • I having been looking every where to see how long your thirsties duo wrap covers last. I have some that have been leaking really bad and before I go trying to find this problem I’d like to know if they are just old and worn out. I have been using them for at least a year and a half. I have five covers I rotate. We cloth diaper during the day everyday. I wash and dry them in the washer and dryer. Thanks!
