Dental Cleaning Waste

General Information

Disinfectants, cleaning solutions, chemiclave solutions and cold sterilants can be hazardous depending on their ingredients and concentrations. 

Some of the most common chemicals of concern are:
• Acetone                • Chromium                    • Phenols
• Ammonia              • Formaldehydes
• Bleaches              • Glutaraldehyde

Before disposing of a solution containing these chemicals, determine if it is a hazardous waste. To avoid using these hazardous chemicals for sterilizing consider converting from a chemiclave to an autoclave. To properly dispose of hazardous waste, contact a licensed vendor.

Line cleansers with bleach can dissolve mercury from amalgam particles in dental wastewater. As a safer alternative, the Department of Ecology's "Best Management Practices for Dentists" lists line cleansers that do not contain bleach or chlorine. The list is on page 7.
