Professional car detailers select targeted products based on materials when cleaning interiors. For leather seats, Swiss-imported elephant tallow leather cream (such as Swissvax 125ml) or German SONAX Nappa-specific care agent is typically used, paired with neutral foam cleaner (like Turtle Wax Big Orange 650ml) for stain removal. For fabric headliners, a high-suction vacuum cleaner is employed with Biaobang 620ml foam cleaner for pre-treatment, while stubborn stains are addressed using Karcher Chemical PO neutral cleaner with a soft-bristle brush. For plastic components, 3M dashboard wax or Goodview 450ml restorer is selected, which both removes fingerprints and forms a dust-resistant protective layer. Regarding rubber trim maintenance, SONAX track lubricant prevents whitening and cracking. For instance, after leather seat cleaning, SONAX coating agent is applied to form a protective layer, whereas wipe products (such as GERTHRON 240-count pack) are only suitable for routine quick maintenance, with deep cleaning still requiring professional solutions. Note that products containing alcohol or strong acids/alkalis should be avoided to prevent interior material degradation, and regular maintenance can extend material lifespan by approximately 30%.
