It is generally recommended to thoroughly clean the car interior every 2 to 3 months, as the interior is the area that comes into closest contact during vehicle use. Benefits of regular interior cleaning: 1. Extends the service life of car interiors: With prolonged use and good window sealing, especially during seasonal changes and high summer temperatures, interiors inevitably accumulate bacteria, dust mites, and odors. Regular interior cleaning can disinfect, remove musty smells and odors, maintain a good cabin environment, and prolong the interior's lifespan. 2. Protects interior surfaces: Interior cleaning typically includes polishing treatment for leather surfaces, providing comprehensive protection. This not only makes surfaces shinier but also forms a protective film to prevent cracking and fading caused by high temperatures, oxidants, and UV rays. 3. Maintains fresh cabin air: Regular interior cleaning keeps the cabin air fresh and the environment comfortable, preventing bacterial harm to occupants and ensuring a pleasant riding experience.

My car is used daily to pick up and drop off the kids, and the back seat always gets covered in cookie crumbs. I basically clean it every three weeks. Especially in summer, if drinks spill, they must be wiped up immediately, otherwise the sugar will stick to the fabric seats and attract cockroaches. Leather seats are actually more hassle-free—just wipe them down with a damp cloth twice a month. However, avoid using cleaners directly after exposure to strong sunlight, as the leather may crack. My advice is to consider usage frequency: if you have pets or often drive through construction sites, vacuum as soon as you notice dust; for those mainly commuting, if you smell AC odors or see the seats noticeably dusty, it’s time to clean—don’t wait until mold grows to regret it.

Last time I saw my friend's car roof molding, he said he hadn't cleaned the interior for three years. Actually, for frequently touched areas like the steering wheel and gear shift, wiping them with wet wipes every two weeks can reduce bacteria by half. Fabric seats are the most troublesome - coffee stains older than two weeks are basically impossible to remove. My experience is to treat stains immediately. For leather maintenance, you don't need to overdo it - professional deep cleaning every six months is sufficient, but use specialized cream monthly to prevent cracking. In cities with poor air quality, I recommend keeping a small car vacuum cleaner for quick cleanups.

It depends on the material: fabric seats tend to accumulate dust, so I use foam cleaner to clean them monthly; leather seats, on the other hand, are susceptible to chemical corrosion, so wiping them with a damp cloth is sufficient. A special reminder for new car owners: avoid cleaning the interior for the first week after applying window film, as moisture seeping into the circuits can cause trouble. For households with allergy sufferers, remember to clean the air conditioning filter when seasons change, otherwise cleaning the seats alone won't help. The most overlooked area is the gaps in the seat belt buckles, where crumbs can attract ants.
