This problem does not seem to be salts. I have used muratic acid and it does nothing. It seems as if this is a shiny sealer or shellac. It only turns white and stats white when you leave something sitting on it. Buckets, furniture, pots ect.
How do I get the white spots off of my bricks. I have a indoor brick veranda. Where ever you put something down on it weather it be a plant or a cooler or even a rug the bricks turn white. The white seems to be something that has been used in the past to seal or wax the floor. I can take a razor...
