The Mattress
The mattress should be cleaned on the bed weekly using a damp soft cloth and
mild detergent. If top cover or base cover becomes grossly soiled, put on clean
gloves, plastic gown and eye protection before removing top and base covers and
disposing according to standard hospital procedures for contaminated waste and
replace with clean covers. The mattress should check and clean each time before
use or once a week.
Covers can be washed and thermally disinfected in a washing machine by
following below procedure: (Never use phenol based cleaning solutions).
