How can I clean the top acrylic?

It is recommended that 2 people do this together by following the steps below: 1. Remove the 4 screws 

1. Then position a person at the foot and the head of the bed. 
2. Lift the acrylic straight up with a hand at each of the four corners. 
3. Move the acrylic out to the front of the bed and rest it on the side edge of acrylic 5. Towels or similar soft fabric should be pre-placed prior to setting the acrylic on it 6. Once the bottom side has been cleaned, place the acrylic back on the bench. Do not 

slide the acrylic while lining up the screw holes. It must be picked up and moved so there is no direct contact with the metal frame until it is aligned with its final resting spot.
