Stains can be caused by different foods (think blueberries), illnesses, medications and other factors. The good news is that stains do not affect the utility of your cloth diapers (and are therefore not covered by warranty) so if they don’t bother you, no action needs to be taken and they will often fade a bit over time and subsequent washes. Stains on your diapers don’t mean they aren’t clean. They do catch poo after all, so some staining is expected at some point or another with most diaper fabrics.
Natural fabrics stain more than synthetics. Minky fabric will not stain at all, no matter what.
To remove stains (if desired), we suggest laying them out in the sun to dry (after washing) for several hours at a time (several times for tough stains). Direct sunlight is actually a very powerful, natural, safe and free way to ‘bleach’ your diapers and remove stains.
If you have a stubborn stain, cut a lemon and squeeze some lemon juice directly on the stain before laying it out in the sun. Re-spray with lemon juice as it sits in the sun to keep it moist. *If you use this method, remember to wash your diapers again before using them on baby*
To sun your diapers, simply lay them out in the direct sunlight coming in from a window or hang them out to line dry or on a drying rack on a sunny patio.
You can also add Oxiclean or another oxygen bleach (not chlorine bleach) to your wash on a regular basis if you want to be proactive.
