Car disinfectant spray is an antimicrobial solution designed to kill 99.9% of viruses and bacteria on high-touch surfaces. It is essential for sanitizing the steering wheel, gear knob, door handles, and touchscreens. The formula is usually alcohol-based or uses quaternary ammonium compounds but is balanced to be safe for automotive plastics and leather, ensuring it doesn’t dry out or bleach the interior materials while keeping the cabin hygenic.
