Does anybody know how to remove a chalky white stuff from slate tile flooring?

A while ago I installed a slate tile floor in my bathroom and I have sealed it too. After having it for a little while a white chalky looking substance started apearing on it, i assumed it was dust though. So when i moped the floor with a little bleach and water it some what went away. After having this floor for months now the white chalky stuff has gotten worse and i even hand scrubed the floor with a rag soaked in water, it apeared as if I was cleaning this chalky substance off, but when it dried it was evident it was still there. Does anyone have any suggestions of how to remove this chalky substance. Thank You.

1. umm well the javel may have permantly bleached your floor. also if you have a dog and it peed on the floor and you didnt notice and it dried up it will have bleached it too. that or the sealer you put on may not have been applied correctly and there is an air space between sealer and tile, you would need to remove the sealer and reaply, or you could call a professional and not ruin your floors more than you may have already. no on can tell you what it is for sure... so be careful!
