What can happen if friction is not applied during valve cleaning?

When friction is not applied during valve cleaning, the cleaning action may not be thorough enough. Effective cleaning relies on the mechanical action of scrubbing or rubbing to dislodge debris and biofilm from the surfaces of the valves. Without sufficient friction, residues—such as blood, mucus, or other contaminants—can remain adhered to the surfaces, making it difficult to achieve a proper level of cleanliness. This incomplete cleaning can lead to hygiene issues and increase the risk of recontamination or infection during subsequent procedures. Therefore, ensuring that friction is applied is critical for achieving optimal cleaning results in valve maintenance.
