Which of the following detergents is appropriate for shell cleaning?

• A. Harsh degreaser
• B. Alcohol-based cleaner
• C. Mild detergent
• D. Solvent-based cleaner

Answer: (C)

Cleaning the outer shell of PPE calls for a gentle cleaner that won’t harm the fabric, coatings, or reflective materials. A mild detergent fits that role perfectly: it lifts dirt and contaminants without aggressive chemicals that can degrade fibers, remove protective finishes, or affect waterproofing. Harsh degreasers can strip protective coatings and weaken the fabric; alcohol-based cleaners can dry out or degrade coatings and adhesives; solvent-based cleaners can dissolve or swell shell materials and leave unsafe residues. So, a mild detergent is the best choice because it cleans effectively while preserving the shell’s integrity and protective properties.
