What is the white substance on car seats that cannot be wiped off?

White substances on car seats that cannot be wiped off are generally stains or paint, which can be removed by polishing, and it's best to apply a layer of glaze afterwards. Below is an extended introduction: Introduction to Polishing: Polishing refers to the processing method that utilizes mechanical, chemical, or electrochemical actions to reduce the surface roughness of a workpiece, thereby obtaining a bright and smooth surface. It involves the use of polishing tools and abrasive particles or other polishing media to refine the workpiece surface. Function of Polishing: Polishing does not improve the dimensional accuracy or geometric shape precision of a workpiece but aims to achieve a smooth surface or mirror-like luster. Sometimes, it is also used to eliminate gloss (matte finishing). Typically, a polishing wheel serves as the polishing tool. Polishing wheels are usually made of multiple layers of canvas, felt, or leather, clamped on both sides with metal discs, and coated with a polishing compound consisting of finely ground abrasives and grease uniformly mixed together.
I also noticed these white stains on my car seat while driving yesterday, and they just wouldn't come off no matter how hard I tried - so annoying! Based on my experience, this could be residue from accidentally spilled sunscreen or cosmetics, as these products contain oils and mineral powders that stubbornly adhere to leather or fabric once dried. Try gently wiping with a damp cloth mixed with baking soda or automotive-specific cleaner, but avoid scrubbing too hard to prevent scratching the seat surface. If that doesn't work, it might be mold growth, especially in hot and humid weather when sweat mixes with dust and promotes mildew. Regular disinfection sprays can help prevent this. For persistent stains, it's best to visit professional auto detailing shops - their specialized equipment won't damage the interior. Whatever you do, don't delay; these stains become harder to remove over time, affect aesthetics, and may even develop odors.
My car is often used to pick up and drop off the kids, and last week I noticed white stains on the back seat that wouldn’t come off. I suspect it’s dried residue from spilled dairy products like juice or yogurt. They stuck to the seat, forming milky stains that wouldn’t budge with regular wiping—I tried wet wipes and soapy water to no avail. Later, a friend suggested using an automotive interior cleaner spray: first testing a small area for colorfastness, then gently rubbing with a soft cloth, which finally removed most of it. Now, I remind my family to eat less in the car and do a quick clean weekly to prevent dirt buildup. I really wish car manufacturers would design easier-to-clean materials, like waterproof fabrics, to reduce such hassles and make life simpler.
