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.
Preventative maintenance should be performed at a minimum of annually. A preventative maintenance pro- gram should be established for all Stryker Medical equipment. Preventative maintenance may need to be performed more frequently based on the usage level of the product.
