What type of material should not be used to clean a safety helmet?

Using abrasive cleaners or harsh chemicals on a safety helmet can compromise its integrity and effectiveness. The materials from which safety helmets are made, such as polycarbonate or fiberglass, are designed to provide maximum protection. When abrasive substances or harsh chemicals are applied, they can scratch the surface, degrade the material, or create micro-cracks that weaken the helmet's structural integrity.

In contrast, using water, non-abrasive cleaners, or soap ensures that the helmet remains clean without damaging its protective qualities. These substances are gentle and specifically suitable for maintaining the helmet's safety standards while ensuring that any dirt or contaminants are removed effectively. Keeping a safety helmet clean without compromising its materials is vital for ensuring ongoing protection in hazardous environments.
