Odor – Fecal and Urine Odor: Procedure for Cleaning

This procedure is for relatively minor fecal and urine odor contamination, like the occasional pet accident, or a person with an illness and had lost continence. Most of the time the carpet and pad are affected. When rodent fecal and urine is involved, like in hidden areas that are discovered, most of the time removing affected drywall is best, and framing is heavily treated with solution chemistry.

For gross contamination, where the load has accumulated over an extended period of time, refer to the Gross Biohazard Procedure in this App.

Supplies:

  • Cotton rags

  • Contractor bags

Equipment:

  • PPE: Half-face respirator, White coveralls, nitrile gloves (6 mil)

  • ULV fogger

  • Spray Bottle

  • Carpet pad remnants

  • Painters Tape

  • Hydrosensor

Chemistry:

  • OdorX Un-Duz-It Unleashed™ Urine Odor and Stain Eliminator

  • Artemis Bio 40-TB

Step-by-Step Instructions

Step 1: Inspect and Isolate

  • Identify sources of fecal or urine odor. This is best done with a Hydrosensor when working with carpet, or visual if in a hidden area that rodents can access. Photograph and document all contaminated surfaces and areas. Map the affected area with painters tape.

Step 2: Safety Setup

  • Wear full PPE. Place HEPA air scrubber in or near affected area and turn on.

Step 3: Remove Source Material

  • Physically remove any visible load. Bag and dispose in contractor bags. If drywall that has been even modestly saturated, consult with the homeowner and recommend cutting out and removing the affected drywall and insulation.

Step 4: Enzymatic Treatment

  • For carpets: Pull back carpet. Treat with Unleashed using a hand spray bottle on the top and backside of the carpet. Repeat twice. Cut out the affected pad. Spray the subfloor with Unleashed. Wet thoroughly. When floor and carpet are sufficiently dry, replace pad with new pad, use painter tape to secure to remaining pad. Reset carpet. Apply enzymatic cleaner to all affected surfaces, including subfloor, baseboards, and furniture bases. Allow 10–15-minute dwell for digestion.

    • This may well require relocating contents. Return them when carpet is restored.

  • For drywall: If damage is minor or surface, treat with unleased using a hand spray bottle. Wet well. Remove any insulation. Allow 10–15-minute dwell for digestion.

Step 5: Disinfection

  • To address the volume airspace, and the structure surfaces, fog with Artemis Bio 40-TB.

Step 6: Documentation

  • Record chemical usage, photos, and client recommendations for repainting and/or flooring replacement.

By following this procedure, strong fecal and urine odors can be safely neutralized at the microbial level, restoring a hygienic and habitable indoor environment.
