Are solvents permitted when cleaning the structure helmet shell?

• A. Yes, solvents are recommended
• B. No, NEVER use solvents
• C. Only solvent-based cleaners
• D. Solvents allowed if diluted

Answer: (B)

Avoid using solvents when cleaning the helmet shell because solvents can damage the shell material, weaken adhesives, and compromise the protective integrity of the helmet. The shell, often a composite or polycarbonate structure with foam and internal components, can be softened, crazed, or delaminated by chemical cleaners, which undermines impact protection and fit. Residues from solvents can also irritate skin or create flammable or off-gassing hazards in heat or fire environments. The safe approach is mild soap and water with a soft cloth, followed by thorough drying, and to always follow the manufacturer’s cleaning instructions. That’s why the correct stance is to never use solvents. The other options imply using solvents in some form, which can risk damage to the helmet and void its protective performance.
