What's the difference between an all-purpose interior cleaner and a dedicated leather cleaner?

All-purpose interior cleaners (APCs) are pH-balanced sprays designed to safely clean plastics, vinyl, fabric, and lightly soiled leather in one step. Dedicated leather cleaners are typically gentler, often paired with a conditioner, and better for soft or perforated leather where an APC can strip oils over time. Specialist detailing communities generally recommend an APC for routine maintenance and a dedicated leather cleaner + conditioner every few months for seats.
