how to fix waterlogged cell phone keys?

[cheetah]

i think a couple of keys on my cell phone have become waterlogged. i have a keyboard phone, and when i press on certain keys (such as e, r, f, and the * key on the main keyboard) it continues to type multiple random keys on its own.

i think the keys have become waterlogged - is there any way to fix this, or do i just wait until it fixes itself and returns to its normal state?
