Cleaning Validation of Garment washing machine and dryer

Dear All,

Anybody has any idea on how to draft cleaning validation protocol for garment washing machine and dryer machine. Like what should be the acceptance criteria for cleaning validation. Should it be only applicable for purified water only or it should include detergent testing. If detergent testing is included then how to have the analytical method for the same.

These machines are used for washing and drying of garments used in formulation for tablet, capsule, oral liquid and external preparation

Awaiting feedback
