Which cleaning agent is recommended for TruDefender?

• A. Hydrogen peroxide
• B. Soap and water
• C. Household bleach (5% sodium hypochlorite) or alcohol
• D. Sand and grit

Answer: (C)

Cleaning agents for TruDefender are chosen to disinfect effectively while protecting the device’s materials and sensitive electronics. Household bleach at about a 5% sodium hypochlorite concentration and alcohol are recommended because they offer broad-spectrum disinfection and act quickly, helping to neutralize contaminants without leaving residues that could interfere with sensors or plastics. Alcohol evaporates rapidly, reducing moisture risk to internal components, while properly diluted bleach can clean and decontaminate surfaces. Hydrogen peroxide can be harsher on some plastics, coatings, or seals used in the device, potentially causing damage over time. Soap and water, while common, may not fully inactivate certain contaminants and can leave films or moisture that aren’t ideal for delicate equipment. Sand and grit would physically damage surfaces and seals.
