Cloth Diaper Laundry Guide

Washing and Stripping Cloth Diapers

For every diaper, there are 5523 different opinions on how best to wash them. So which advice should you follow?
I recommend customers follow the manufacturer's recommended wash routine. For one, they are the holders of the warranty. If their instructions are not followed, they can (and often do) void the warranty. Most importantly, however, the manufacturers have spent years researching and testing what works with their product. They know better than anyone what will work to keep those diapers squeaky clean.
Here are specific instructions from each of the manufacturers that Bumbini carries. Note: stripping instructions are included in case you need to strip due to smells or repelling - it does not need to be done on a regular basis. If you do find you need to strip often, please contact me and we will tweak your wash routine.
Recommended Wash Routine:
  1. Prewash cold
  2. Heavy duty wash hot with the recommended amount of detergent
  3. Double rinse (very important to prolong the life of PUL)
  4. Hang dry if possible, or dry on delicate cycle. Inserts can be dried medium.
Detergent Recommendations:
  • Zero reside. No perfumes, fabric softeners, natural oils, dyes, enzymes, UV brighteners or stain guard ingredients.
  • Do not use bleach, products with sodium percarbonate (oxygen bleaches) or RLR. Use caution when adding vinegar or baking soda.
Stripping instructions: (From Applecheeks Blog)
  1. Cold pre-rinse.
  2. Add usual detergent plus 1/2 cup of baking soda. Do a heavy hot wash
  3. Do a second heavy hot wash with no detergent and 1/2 cup baking soda
  4. Run as many heavy hot water washes with nothing added until the diapers smell REALLY clean (1-3 additional cycles)
Washing instructions:
  1. Cold pre-rinse (or cold quick wash) with no detergent
  2. Warm or hot wash with additive free detergent. Use the highest water level possible.
  3. Rinse twice.
  4. Tumble dry inserts, line dry cover (or tumble on low)
Detergent recommendations:
  • No fabric softeners, bleach, vinegar, baking soda, washing soda, borax, oxyclean etc.
  • Additive-free detergent is recommended. Best Bottom has done extensive testing with Tide Original and recommends it for their diapers.
Stripping instructions: (from Official Best Bottom Facebook Chat Group)
For smells with no repelling/leaking:
  • Possible cause: urine buildup
  • Solution: add more detergent to wash cycle and ensure you are using the highest water setting. Also, start wash routine with a quick cold wash to make sure all urine and solid matter is flushed out before full wash.
For smells WITH repelling and leaking:
  • Possible cause: the buildup of minerals, creams or laundry additives
  • Do a deep cleaning:
    1. Start with clean diapers
    2. Do several hot washes with twice the amount of recommended detergent.
    3. Do 2-3 hot washes without detergent.
  • Handwash inserts in a tub with Dawn Blue dish soap to break down detergent or creams that could be built up in the insert. Rinse well, and do several rinse cycles in the washing machine.
BumGenius Washing instructions:
  1. Prewash cold or warm with 1/2 amount of detergent recommended for a full-size load.
  2. Heavy duty washes on hot with enough detergent for a heavily soiled full load.
  3. One cold rinse
  4. Line dry covers/shells, tumble dry inserts.
Detergent recommendations:
  • Whatever works for your family, but cautions against using detergent with perfumes, dyes, optical brighteners or fabric softeners.
Stripping instructions:
No specific "stripping" instructions found, but BG recommends adding 1/4 cup of bleach to wash load monthly.

Detergent recommendations:

  • Do not use baking soda or vinegar unless specifically suggested by the manufacturer.
  • Bleach alternative (sodium carbonate or sodium percarbonate) can be used on occasion for stain removal)
Stripping instructions:
For suspected detergent residues (repelling, smell, rashes) - wash several times in hot water with no detergent. Make sure you are using enough water to rinse out all detergent in future wash routine.

Use one packet of RLR per 20 diapers

Bleach soak:
Use disinfecting bleach (will say disinfecting/kills bacteria etc. on the label)

Detergent recommendations:

  • Do not use vinegar on a regular basis.
Stripping instructions:
  • If a detergent residue is suspected, wash on warm without detergent. Stop machine mid wash cycle and observe if there are bubbles/foam. If so, continue doing washes with just water until the water is clear.
  • For other residues, strip diapers using 1/4-1/2 cup of oxygen stain cleaner and white vinegar (1/8 cup in HE). Wash several times after in clear water to make sure all residues are removed.

  • Recommended to strip every 3 months to prevent buildup problems
    1. Do 2-3 hot washes with no detergent
    2. Tumble dry until dry and then 15 minutes longer (to fluff up pile)


Even the manufacturers disagree on the best method - a fact that made my head hurt compiling the information for this post. There are many reasons for this. Different brands of diapers are made from different materials. Even the same material may differ between suppliers, for example, Applecheeks PUL may be entirely different than Best Bottom PUL. So while instructions may be perfectly sound for that particular brand, it may not be fantastic for another brand.
There are lots of groups on the internet that guide people to the perfect wash routine. However, a lot of their advice can be harmful to the diapers and void any warranty you may have, especially advice regarding stripping and bleaching. Several manufacturers have many unhappy customers with diapers with extensive damage from following this well-meaning advice. And unfortunately for the customer, this damage is not covered under warranty. If your goal of cloth diapering is to save money, keeping those diapers in good condition is a good way to do it!
As always, if you have any questions, please don't hesitate to contact Bumbini :)
