Ok, lets think of the following. In the case you are using a kind of
washing powder it might be that there's an amount of Iron (Fe) present
(next to K, wich the partial reaction
Fe -> Fe2O3 takes place. This is just the formation of 'rust'. If it
isn't Iron it might also be Manganese, but this is rather doubtfull.
Anyway, search in this direction. And don't forget, there are still
more healthier alternatives to these artificial detergents, like
'Savon de Marseille' !

If u're ever going to bleach with hydrogen-peroxide (HOOH). Be
carefull and store it wise !

ooo so OCl- is the chemical makeup of bleach
