Hello, we installed a brand new ceramic tile walk in shower about one year ago. I've been cleaning it with a special cleaner for ceramic tile and it does okay. I bought an electric scrubber to make the job easier, and for some reason, and I don't know if it's related, lately I can have the shower perfectly clean, beautifully scrubbed, and then after one shower, it's covered with a white residue. I've cleaned the tile with vinegar, I've tried Lime-Away, and CLR, and after I rinse it and let it air dry it looks fantastic. Then if someone takes a shower, as soon as it's dry it looks terrible. We have a well water that goes through a very robust filter. We also have a water softener unit which we're not sure is functioning properly, and I asked my husband to bypass it and see if that would make this residue go away, thinking maybe it was salt. Well that actually made it WAY worse. I am completely at a loss.
