While chlorine-based compounds such as bleach are often used to decontaminate surfaces, they are known to degrade plastics and may leave harmful residues and release potentially irritant vapors making them unsuitable disinfectants for materials that come in direct contact with humans. The objective of this study was to evaluate an alternative urine disinfection procedure. Treating urine-contaminated surfaces with 3% hydrogen peroxide (H₂O₂) was hypothesized to remove bacteria. Furthermore, when applicable, the efficacy of the same H₂O₂ stock solution for its repeated use over time was assessed further increasing simplicity and accessibility.</div></div><div><h3>Materials and methods</h3><div>The effectiveness of disinfecting two materials, a flat plastic surface and a long lumen representing a more challenging surface to clean, was evaluated with a commonly used method of water and soap versus using a 3% H₂O₂ solution.</div></div><div><h3>Results</h3><div>Contamination persisted when washing with soap and water but was effectively removed after one hour of H₂O₂ storage for flat plastic surfaces and after 3 hours for lumen surfaces.
