Flush solid poop down the toilet. Poop from exclusively milk-fed babies (no solid foods) can remain on the diaper.
Use free and clear detergent. Add as much detergent as suggested on the bottle. NOTE: Too little detergent causes ammonia buildup, resulting in rashes and unpleasant odor on the diapers.
Machine wash HOT and tumble dry. Add a cold rinse before and/or after washing.
Do NOT use fabric softener or dryer sheets. Diluted bleach may be used occasionally if necessary, but may stain your diapers.
How to Wash Wool Products
Wool products MUST be lanolized at least once before first use. Follow directions starting at Step Three and repeat until wool is water-repellant. Thereafter, lanolize once every 4 weeks.
If the wool is soiled or dirty, flush solid poop down the toilet. Rinse the diaper and clean by hand with wool wash. Hang to dry.
For wool that has only been peed on, hang to dry overnight. Unless it is soiled or dirty, wool can be reworn without washing for up to four weeks. At that point, proceed to the next step.
Melt lanolin and water in the microwave, using about a teaspoon of lanolin.
Add a capful of wool wash, then pour the mixture into a large bowl and stir until foamy.
Add ice cubes until the water is tepid (lukewarm). Add an extra cup or two of tepid water as necessary.
Let sit for 2-3 hours. If lanolizing brand-new wool, let soak overnight. Squeeze the wool gently before leaving it to soak. Afterwards, do not wring the wool. Roll between towels and lay flat to dry.
