Dried Blood Removal from a Polypropylene Carpet in Claverdon

Professional Blood Contamination Cleaning

This case study concerns dried blood contamination on a polypropylene carpet at a property in Claverdon.

The carpet had numerous small spots of dried blood together with two larger patches. Because the blood had dried into the fibres, the first stage was to soften and treat the contamination before extraction.

The Carpet Before Cleaning

As you can see from the photograph, the contamination was spread across a relatively large area rather than being confined to one isolated spot. The two larger patches were particularly noticeable, with numerous smaller spots extending across the carpet.

Aggressive scrubbing was avoided. The aim was to loosen the dried contamination and remove it through controlled extraction.

Step 1 — Sanitising & Softening the Dried Blood

A suitable sanitiser was applied to the affected areas.

The product was allowed to soak into the carpet and given time to work.

This provides the necessary sanitising treatment while the moisture also helps to rehydrate and soften the dried blood, making it easier to remove during the rinsing stage.

Allowing the treatment time to work was particularly important here because of how dry and established the blood had become.

Step 2 — Cold-Water Rinsing & Extraction

After the treatment had been allowed time to work, the affected areas were rinsed and extracted using professional carpet cleaning equipment.

Cold water was used for this stage.

Excessive heat can cause blood proteins to coagulate and potentially make staining more difficult to remove, so water temperature is an important consideration.

The objective was to flush the loosened contamination out of the polypropylene fibres rather than simply spreading it across the surface.

Step 3 — Water Claw Extraction

Once the cleaning and rinsing stage was complete, there was still moisture within the carpet.

A Water Claw was used to extract additional moisture.

This is an important part of the process, particularly when carrying out a deeper clean. Removing additional moisture at this stage helps reduce drying times and leaves less water within the carpet.

Step 4 — Complete Drying

After Water Claw extraction, fans/air movers and towels were used to continue drying.

The carpet was worked until it was completely dry.

Removing visible contamination is only part of the process. Moisture recovery and thorough drying are also needed to complete the treatment.

The Result

The treatment followed a methodical sequence to address both the dried contamination and the moisture introduced during cleaning.

The carpet had numerous small dried blood spots as well as two larger patches, but by working through the process of:

Sanitise → Soften → Cold-water rinse → Extract → Water Claw → Dry

the affected carpet could be thoroughly treated and cleaned.

The final stage was making sure the carpet was completely dry, using professional extraction equipment, a Water Claw, fans and towels.
