How do you disinfect alginate impressions?

To disinfect alginate impressions, first rinse the impression under cool running water to remove any debris. Then, immerse the impression in a disinfectant solution approved for use on dental materials, such as a 1:10 dilution of chlorine bleach or a commercial disinfectant, for the recommended time (usually around 10 minutes). Ensure that the disinfectant is compatible with alginate to prevent distortion. After disinfection, rinse the impression again with water to remove any residual disinfectant before pouring it with stone or plaster.
