• Ultrasonic Solutions — A solution for an ultrasonic bath, a device that removes debris by a process called cavitation. Automated cleaning of this kind does not require presoaking or scrubbing of instruments.
• Enzymatic Cleaners — A detergent with enzymes in it: enzymatic cleaners are not disinfectants. Neutral pH detergent solutions that contain enzymes are compatible with metals and other materials used in medical instruments.
• Cleaning Accessories & Solutions — What hand cleaning is done with: a long-handled brush that keeps the hand away from sharp instruments, and heavy-duty gloves.
• General Cleaning Liquids — A plain detergent or surfactant solution, the kind scrubbing is done with.

Method first: what to weigh in selecting cleaning methods and equipment is how well the method works, whether it suits the items being cleaned, and the occupational health and exposure risks.

Material compatibility: a neutral or near-neutral pH detergent is commonly used for instruments, while alkaline-based cleaners dissolve protein and fat residues efficiently but can be corrosive. Two studies found no difference in cleaning efficiency between enzymatic and alkaline-based cleaners, and another found no significant difference between enzymatic and non-enzymatic cleaners in microbial cleaning efficacy.

Residue: enzymes and chemicals are rinsed from the equipment, because residue can lead to adverse reactions.

Checking the result: no real-time test exists that can be used in a clinical setting to verify cleaning, so at a minimum every instrument is individually inspected and has to be visibly clean.
