Professional Carpet Cleaning Guide – Biohazard Stains (Blood, Faeces, Urine)
Note: Multiple applications may be required to reduce staining. PPE must be worn and all equipment disinfected after use. Biohazard training is recommended.
Step 1: Prepare Pre-Spray Solution
Mix High Power Urine Neutraliser and Mattress Pre-Spray at 500ml per litre of water.
Step 2: Apply Pre-Spray
Apply a heavy amount of pre-spray to the affected area using overlapping passes.
Allow the solution to dwell for 15 minutes, during which it will break down soils.
Step 3: Agitation (Optional)
After dwell time, use manual or mechanical scrubbing methods to further agitate the carpet fibres.
This step is not always necessary, depending on the severity of the staining.
Step 4: Rinse Extraction
Prepare your rinse solution by mixing WS Stain Repel Rinse at 30ml per 10 litres of clean water.
Rinse extract the carpet slowly and methodically using your cleaning wand.
Step 5: Cleaning Passes
For every wet pass, follow with at least two dry passes to help remove residual moisture and soils.
Step 6: Repeat if Necessary
If staining or residue remains, repeat Steps 2–5 until the area is clean.
Step 7: Deodorising
High Power Urine Neutraliser and Mattress Pre-Spray will deodorise the area.
