Thanks to Shannon for this Frugal Baby Tip!
Someone asked a while ago about sun bleaching diapers and how/why it works. I will try to explain it but it has been a long time since my days in the biochemistry lab and I may not have it totally accurate.
Colors (i.e. stains) show up because the chemical structure has a "ring" of atoms with a particular resonant frequency that will only allow certain light waves to pass through. The frequency of the light is what our eye perceives as color. So the sun has photons in the light rays that will interrupt the resonant frequency of the "ring" so that all light can pass through and it then appears white. Bleach does the same thing only using the negative chlorine ion to interrupt the resonant structure.
This is probably more than anyone wanted to know! Sun bleaching does weaken the fabric just like chlorine bleach - probably not as quickly though. I don't bleach my diapers sun or otherwise. I just make sure they are washed well. I live with the brown stains but don't particularly like them. I think I might try making some diapers in a really dark color that won't show the stains!
Perhaps purple! LOL
