ii. washing cages
a. for smaller cages, clean by using the mechanical cage - washing device (wash and rinse cycles). larger cages and kennels will need to be washed by hand. use the portable pressure washer to dispense detergents and disinfecting chemicals followed by a clear water rinse.
b. to thoroughly sanitize the cages, use an approved disinfecting solution. leave the chemicals on the surface of the caging for the appropriate amount of time. this ensures disinfection has occurred (refer to the product guidelines to determine the time). then, rinse the cages with water that is 180°f or higher. do this for at least three minutes to make sure all chemical residue has been removed.
c. note that some animals, including rabbits and some rodents, produce urine that is high in proteins and minerals. these compounds often stick to the surface of the cages. if this happens, the cages will need treatment with an acid solution prior to washing.
