Cloudy Blue Pool

I wonder how much of the fading is due to chlorine and how much is due to the sun. I know that I've had the backs of sofas fade when exposed to the sun, without ever coming into contact with bleach at all.

Yeah, I know the deal about fading has been around for years in swimming pools. my problem with it is when you wash your clothes in the washing machine with the Clorox recommended dosage, that calculates out to (I think) about 187.5ppm of chlorine for a fairly long exposure (and with no CYA). That makes me question the ability of 25ppm chlorine to fade clothing.

Fading of suits with no CYA and FC levels of 2 or 3 is well documented. The whole point of putting bleach in a washing machine is to turn things white. If you want to maintain colors you use "color safe beach" which is really a different chemical. Fading with mid range CYA and high levels of FC is more theoretical than proven.

There is much more discussion of this whole subject here.
