I don't have kids but have bought Napisan to use when washing sheets/towels etc. after many, many recommendations on here. But it's still not clear to me if it's ok to use it when washing coloured items? The box says to not use for "non-colourfast" items... Most of my bedding and towels are colours rather than whites.
As far as I can see, there are no bleaching agents in Napisan so should be ok?
