Tronman 14 Report post Posted April 9, 2006 They my be thinking of a diluted hydrochloric acid cleaning. When cleaning grout smears etc from floor tile you can use Sulfamic acid or Phosphoric acid. I like the Phosphoric because it is strong but not in the range of hydrochloric or muratic. Share this post Link to post Share on other sites
