80% is high enough to cause you problems and you need to keep it in the 50% range for sure.

Damp Rid is sold in Home Depot and just about anywhere else for that matter.

It is a quart sized container that you fill (and re-fill) with moisture absorbing pellets.

The pellets absorb the moisture out of the air and it condensates until the container fills up with water. Then, you pour off the water and use again.

Check it out on the net.
