Learn how to prep Cloth-eez Birdseye Flats and Absorbers for first use and build a simple flat diaper wash routine that keeps absorbency strong.
Quick answer
Prep new Cloth-eez Birdseye Flats by washing them separately two to three times in hot water with a small amount of detergent, then dry fully. Wash used flats and Absorbers together in a routine that includes a prewash, a hot main wash, and a thorough dry.
Why birdseye flats and stretchy absorbers need different prep
Cloth-eez Birdseye Flats are woven cotton, so their absorbency builds gradually as the fibers relax and the natural cotton oils are removed. The white version is chlorine-free and optical brightener-free, which means it preps easily and looks like classic white cotton after a few washes.
Cloth-eez Absorbers are a different fabric: two layers of 92% cotton and 8% Spandex at 280 gsm. The Spandex gives a soft stretch that makes a snug fit less binding, but it also means you should avoid very high heat and harsh additives that can degrade elastic over time. Prep them gently and keep them out of the dryer on high.
Build a wash routine that protects absorbency
A simple flat diaper wash routine works for both flats and Absorbers: a short prewash to remove the bulk of soil, a hot main wash with detergent, and a second rinse if your machine allows. Skip fabric softener and dryer sheets, which coat cotton fibers and reduce absorbency.
Wash frequency matters more than a complicated routine. Aim for every two to three days so diapers do not sit long enough to develop odors or stains. If your water is very hard, use a detergent formulated for hard water and check for mineral buildup on the flats.
Step-by-step prep and wash routine
- Prep new flats separately: Wash new Cloth-eez Birdseye Flats alone two to three times in hot water with a small amount of detergent. This removes natural cotton oils and opens up the fibers so the flats absorb instead of repelling. Check absorbency by dropping water on a dry flat; if it beads up, wash it again.
- Prep Absorbers gently: Wash new Cloth-eez Absorbers once in warm water with detergent, then air-dry or tumble on low. Avoid hot water and high heat, which can stress the Spandex over time. Keep Absorbers out of a hot dryer even when you dry flats on higher heat.
- Shake solids into the toilet: Before washing, shake or scrape solid waste into the toilet. For breastfed newborns, you can usually skip this step and wash directly. Never rinse poopy diapers in the sink where food is prepared; use a utility sink or diaper sprayer.
- Run a short prewash: Run a cold or warm prewash with a small amount of detergent to remove the bulk of soil before the main wash. If the prewash water looks very dirty, repeat it before moving on.
- Wash hot with detergent: Run a hot main wash with the full detergent amount for your load size and water hardness. Use a detergent without fabric softener or optical brighteners. Check your machine's load size; too many diapers means poor agitation and leftover residue.
- Rinse and check for suds: Follow with a second rinse if your machine allows. If you see suds in the rinse water, run another rinse until the water runs clear. Residual detergent can cause smells and reduce absorbency over time.
- Dry flats fully, Absorbers gently: Tumble flats on medium or high heat or line dry. Dry Absorbers on low heat or line dry to protect the Spandex. Damp diapers develop mildew quickly; make sure everything is completely dry before storing.
