Interesting. I am sure there are some variables we are not accounting for. IE. on the funnels that I have seen stained, the water tends to bead up, so we end up with beads forming where I assume any previous beads have dried. After many uses the build up gives a stain perhaps. Maybe it is important whether the surface is wetted or not, if it wets then it is spread out, but if it does not, it get concentrated into one small spot as it drys. Another possibility is that it may be very dependent on size of the particles, smaller particles remain invisible, or maybe larger particles easily wash off. I really don't know. I just checked and found that we use three funnels. I am not sure of the material each is made of, but one is blue and the other two are white. Interestingly the white funnels have lots of black stains from the silver, but the blue one has absolutely none. Other than the color the materials seem to be the same, but I guess they probably are not.
Possible differences I can think of are, material, charge on the material, added coloration, texture (although both appear slick), wetability. Maybe only one time doesn't cause visible stains. Our experience is with funnels at are used several times a week. If the one time stain was with wateroz, then maybe CS will not stain with only one application. It is my understanding that wateroz contains other minerals, so that would be a whole other ballgame.
