I agree. You could even add white flour or corn starch to absorb the liquid. If the humidity is high, make a drier mix to start with and leave the lid off until the media has cooled and absorbed all the water. You should be able to turn it upside down without it falling out.

To the OP, even though I have low humidity in the house and more often have cultures dry out, I still have problems with any paper products. Excelsior works very well. You could also try some vinyl window screen. I bleach and re-use my containers and would do the same with window screen.
