Alternatively, you can use another cloth to remove the excess moisture.
Periodic Structural Checks
The most important thing that you can do is to keep a close eye on the structure and stability of the bed. Give it a thorough one over every two-three months to check for loose nuts, bolts, and other connectors. Repair and replacement part that seems loose or faulty. This will keep the bed stable and secure at all times.
