I own a 25 year old home with a garage under the bedroom. My tools are
rusting, just by being stored in tool boxes in the garage. I live in
Nebraska and have never had this problem before. Moisture gets in in the
winter from snow carried in by my wife's car. In the summer, the warm
outside air seems moist. A relative humidity meter (I purchased and placed)
on the wall rarely goes as low as 60% and is usually above 70% and sometimes
above 80%. I can buy and use a dehumidifier in the summer (I am told trying
to use them in the winter can damage the unit).

Do I have other options? Are there granular or other products that will
draw the moisture out of the air? Is there a reasonable way to minimize the
moisture my wife's car brings in (or isn't this the culprit)?

Thanks in Advance.

Respectfully,
Andy

Some possible solutions: a portable electric roll-around dehumidifier (but
you have to keep emptying the pan under it), a wall or window mounted
exhaust fan that sucks dry air, say from under a slightly open garage door,
out thru a window, a garage heater (in Denver we had hot water heating in
the garage, as a branch of the heating system). You could also leave snowy
cars outside long enuf to let it melt off, or just jet it off with a hose,
and let it drip before driving the car inside. Look also at some way to get
the garage air circulating, with fresh air coming in, or check that the roof
and garden drainage around your garage is away from the foundation, and away
from the garage, in all directions.
Cheapest solution... Move the tools you care about inside.

I doubt your wife's car is the culprit. How about a ventilation fan
that turns on when outdoor air contains less moisture than indoor air?

Smart Vent makes one.

Can you please point me in the right direction to buy the fan with the
appropriate sensor?
Thanks in advance.
