Saturate the soiled area. When treating carpets cover 2x the size of the mess. Wait around 10 minutes for enzymes and pro-bacteria to break down the organic proteins. Blot excess moisture with a colour-safe cloth. Allow the area to dry naturally which may take 24-48 hours. Once dried the stain and odour will have disappeared.
If the area is dry but the odour persists, the odour source was not completely penetrated. Re-treat and be sure to completely saturate the soiled area down to the odour source.
