What not to use when cleaning car interior?

When cleaning car interiors, avoid using inappropriate cleaning agents and methods, and treat different materials differently. Do not use general-purpose cleaners containing alcohol, strong acids, or strong alkalis, especially on leather seats and dashboards, as such cleaners can accelerate leather aging or cause plastic parts to fade. When cleaning fabric seats, do not rinse with water directly or scrub vigorously with a stiff brush, as this may cause fabric deformation or internal mold growth. For areas with dense electronic components such as the centre console, avoid wiping with wet towels or allowing cleaning agents to seep into gaps to prevent circuit short circuits. When cleaning carpets, do not soak them completely or scrub aggressively, otherwise the adhesive layer may peel off and they will be difficult to dry. Additionally, mixing different cleaning agents or applying heat may produce harmful gases, while excessive use of care products like dashboard wax can make surfaces sticky and attract dust. It is best to have a professional deep cleaning every six months. For routine maintenance, use material-specific cleaners such as synthetic fibre cleaners for carpets and pH-neutral leather conditioners for leather seats, ensuring thorough ventilation and drying after cleaning.
