Cleaning and Disinfecting
Cleaning and disinfecting are separate processes. Cleaning must precede disinfection. Before
use by a different individual: clean, disinfect, and check product for proper functioning.
Cover Care: Before cleaning and disinfecting, remove the contoured foam base and the cushion overlay
from the cover. Remove the hook fastener pieces from bottom of the cover.
To Clean the Cover: Machine wash in cold water (30°C) with mild detergent,
gentle cycle, or wipe clean with neutral detergent and cold water.
Tumble dry low.
To Disinfect the Cover: Hand wash in cold water (30°C) using 1 part household
liquid bleach per 9 parts water. Keep the product wet with the bleach
solution for 10 minutes, and then rinse thoroughly. Or machine wash in
hot water (60°C). Tumble dry low.
Follow the safety guidelines on the bleach container.
Cushion Care Cautions:
Valve(s) must be closed. DO NOT allow water or cleaning solution to enter the cushion overlay. DO NOT
machine wash or machine dry the overlay or the contoured foam base. Use of the following may cause
damage to the cushion: abrasives (steel wool, scouring pads); caustic, automatic dishwasher detergents;
cleaning products that contain petroleum or organic solvents, including acetone, toluene, Methyl Ethyl
Ketone (MEK), naphtha, dry cleaning fluid, adhesive remover; oil-based lotions, lanolin, or phenolic-based
disinfectants; ozone gas; ultraviolet light cleaning methods.
To Clean the Overlay: Carefully remove the cushion overlay from the contoured foam base. Close the
inflation valve. Hand wash, using mild liquid hand soap, hand dishwashing liquid, laundry detergent, or a
multipurpose detergent (Follow product label instructions.) Gently scrub all cushion surfaces, using a soft
plastic bristle brush, a sponge or a cloth. Rinse with clean water. Air dry.
To Disinfect the Overlay: Repeat cleaning instructions, using 1 part household liquid bleach per 9 parts
water. Keep the product wet with the bleach solution for 10 minutes. Rinse thoroughly with clean water.
Air dry.
Follow the safety guidelines on the bleach container.
To Clean the Contoured Foam Base: Remove the cover. Wipe gently with a cloth
dampened with water and a household detergent. Rinse cloth and re-wipe. Allow foam
to air dry thoroughly before putting the cover on.
This symbol means, "Wipe with a damp cloth."
Disinfectants are not effective on porous surfaces such as foam. If the foam portion of the product
becomes soiled or contaminated, DO NOT use with multiple individuals. Replace soiled or
contaminated foam components.
Note: Most germicidal disinfectants are safe if used following the disinfectant manufacturer's dilution
directions.
Note About Sterilization: High temperatures accelerate aging and will damage the product as-
sembly. ROHO products are not packaged in a sterile condition, nor are they intended or required
to be sterilized prior to use. If institution protocol demands sterilization: First, follow the cleaning
and disinfecting instructions; then, open the inflation valve and use the lowest possible sterilizing
temperature, but not to exceed 70°C (158°F), for the shortest time possible. DO NOT autoclave.
