Urine Cleanup with Hydrogen Peroxide: A Powerful Solution for Removing Urine Odour

When it comes to urine cleanup, standard household cleaners often fall short—especially in severe cases involving long-term contamination. At Biohaz Forensic Cleaning, we use specialist methods and chemicals to tackle the problem at its source. One of the most effective products in our toolkit is hydrogen peroxide, particularly for removing urine odour that has seeped into floors, substructures, and porous surfaces.

Urine, whether from people or animals, can soak deep into timber, concrete, carpets, and underlays. Over time, bacteria in the urine break down and produce strong-smelling compounds like ammonia. These odours are not just unpleasant—they can also be a sign of deeper biological contamination.

Why Hydrogen Peroxide Works for Urine Cleanup

Hydrogen peroxide is a powerful oxidiser that chemically breaks down the uric acid crystals and bacteria that cause lingering smells. When applied during a urine cleanup, it penetrates the affected material, kills bacteria, and helps lift organic matter to the surface. The bubbling reaction you often see is the peroxide actively working to break down contaminants.

In one of our recent jobs, we treated a heavily urine-affected timber floor. As soon as we applied hydrogen peroxide, the surface began to bubble—showing just how deeply the urine had soaked in. After several rounds of treatment and high-pressure extraction, the odour was greatly reduced.
