Gentle Cleaning Formula
pH-neutral shampoos are formulated with low cleaning strength, which is beneficial for delicate surfaces. However, to effectively remove dirt from the surface, mechanical action is required. Tools like sponges or brushes enhance the effectiveness of the shampoo, helping to lift dirt and debris more efficiently from the surface.
Need for Physical Friction
Unlike chemically strong solvents, pH-neutral shampoos rely on physical friction for dirt removal. Sponges, brushes, or cloths provide the necessary mechanical contact, boosting the cleaning power and ensuring that dirt is effectively dislodged and removed from the surface.
Ineffectiveness on Stubborn Dirt
While pH-neutral shampoos are effective for light dirt and dust, they may not be sufficient for stubborn grime, grease, or tar. Such contaminants require additional physical effort for removal. Sponges or brushes help break down and lift these tougher stains, ensuring a thorough and efficient cleaning process.
