Hi. In my bathrooom I have a mirror which was glued on the wall tiles
using silicone. It pretty much fits on the wall (maybe 1-2 millimeters
gap). Under the bottom , left and right sides of the mirror I see some
gray substance. It probably is mildew or rust because of the humidity
formed when bathing. Two questions:
1. how can i clean this ? (however, it is not much, so I wouldn't mind
leaving it there)
2. how can i prevent it from spreading? I thought of sealing the 3
sides with silicone and leaving the top one unsealed so that any
humidity trapped can escape. If humidity occupies space from bottom to
up, then sealing the sides would be fine.
Your comments please

If this is on the back side of the glass, the silvering is going bad
on the mirror. It sometimes just happens but Windex will kill it very
fast. If you must use a window cleaner, don't let it get to the
Well, you have suggestions on how to get the cleanup done.
To stop it from happening, you need to do two things.
1. Open the door after a bath or shower, to let the concentrated humidity
out of a small space.
2. Run a fan, so that the humidity moves away from the room.
The bathroom fan will not do the job, unless you have a very good vent and a
very good fan.
Common silicones cure by reacting with moisture and release acetic
acid. The (vinegar) acid is volatile and will probably dissipate
quickly before any significant effect on the mirror coating. Worth a
try, since the mirror protective layer may already be history.
