STEAM CLEAN, PRESSURE WASH, HOSE OFF OR ULTRASONICALLY CLEAN. Using these methods
of cleaning is not recommended and may void this product’s warranty.
Clean Velcro AFTER EACH USE. Saturate Velcro with disinfectant and allow disinfectant to evaporate. (Ap-
propriate disinfectant for nylon Velcro should be determined by the hospital.)
In general, when used in those concentrations recommended by the manufacturer, either phenolic type or
quaternary type disinfectants can be used. Iodophor type disinfectants are not recommended for use be-
cause staining may result. The following products have been tested and have been found not to have a harm-
ful effect WHEN USED IN ACCORDANCE WITH MANUFACTURERS RECOMMENDED DILUTION.*

Quaternary Germicidal Disinfectants, used as directed, and/or Chlorine Bleach products, typically 5.25% So-
dium Hypochlorite in dilutions ranging between 1 part bleach to 100 parts water, and 2 parts bleach
to 100 parts water are not considered mild detergents. These products are corrosive in nature and
may cause damage to your stretcher if used improperly. If these types of products are used to clean
Stryker patient handling equipment, measures must be taken to insure the stretchers are rinsed with clean
water and thoroughly dried following cleaning. Failure to properly rinse and dry the stretchers will leave a cor-
rosive residue on the surface of the stretcher, possibly causing premature corrosion of critical components.
NOTE
Failure to follow the above directions when using these types of cleaners may void this product’s warranty.
REMOVAL OF IODINE COMPOUNDS
This solution may be used to remove iodine stains from mattress cover surfaces.
1. Use a solution of 1−2 tablespoons Sodium Thiosulfate in a pint of warm water to clean the stained area.
Clean as soon as possible after staining occurs. If stains are not immediately removed, allow solution to
soak or stand on the surface.
2. Rinse surfaces which have been exposed to the solution in clear water before returning bed to service.
