UV, not age
Sun is what kills automotive leather. It dries the topcoat, which becomes brittle, and then normal flexing cracks it.
A car parked outside facing south does this several times faster than a garaged one.
Leather fails by drying, cracking and losing its topcoat, mostly from UV and from cleaners that are too aggressive. It wants a gentle clean and a conditioner, not a shine product.
Cloth fails by absorbing — spills, oils from skin, and the gray that comes from all of it accumulating. It wants extraction periodically rather than conditioning.
Most cars sold in the last decade with what looks like leather actually have leatherette, a coated vinyl. It is closer to a hard plastic than to hide, and treating it with a hide conditioner does nothing useful.
Leather protection is a $25 to $45 add-on depending on vehicle size. Cloth is handled with extraction at $25 per seat. Which one you need starts with knowing what you actually have.
Almost all modern automotive leather is pigmented or coated leather: real hide with a polymer topcoat sprayed over it. You are not touching the hide when you clean it, you are touching the coating. That is why aggressive cleaners are so damaging — they remove the coating, and everything after that goes straight into the hide.
Leatherette — MB-Tex, V-Tex, SofTex, Sensatec and every other brand name for it — is a coated fabric. It is durable, it does not need feeding, and a hide conditioner just sits on it. Clean it like a hard surface and protect it against UV.
Unfinished, aniline or nubuck leather shows up in some higher-end and older cars. It is absorbent and it stains from water alone. If you think you have it, tell us before we touch it; the method is completely different.
The simple test: put a single drop of water on an inconspicuous spot. If it beads and sits, you have a coated surface — leather or leatherette, both handled the same way for cleaning. If it soaks straight in and darkens, stop, and tell us.

All-purpose cleaner, household degreaser and anything alkaline strips the topcoat. The seat looks brilliant for a week, then the bolsters start crazing.
This is the single most common self-inflicted leather damage we see.
New denim into a light seat. Once the topcoat is thin, the dye goes into the hide and it is permanent.
A protectant is the fix, and it has to go on before the transfer, not after.
The driver's outer bolster wears from getting in and out. Purely mechanical, and no product prevents it entirely.
Conditioning keeps it supple, which slows cracking at the wear point.
Ventilated seats have thousands of holes that fill with product and dirt. Liquid cleaner pooled in them is worse than the dirt.
Perforated seats need a drier method and less product, not more.
Greasy, shiny seats are not healthy seats. Excess conditioner sits on the topcoat, attracts dust and makes the surface slippery.
Thin, even, buffed off. That is the whole technique.
Cloth is more forgiving day to day and less forgiving of neglect over years, because everything it absorbs stays in it.

| Interior Detail (base, includes a leather clean and condition) | $229 | $250 | $300 |
A standard interior detail already cleans and conditions leather. The add-on is the protective layer on top, worth it on light-colored hides and cars that live outside, not necessary on every car.
Two things about this city work on your seats specifically. The first is parking outside, which most of us do. Sun through glass is the main enemy of leather and of dashboard plastics, and a car on a west-facing street takes it every afternoon.
The second is damp. Fog, wet shoes, wet dogs, and rubber mats that trap water under them mean cloth interiors here stay wetter for longer than they would inland. That is a smell risk more than a stain risk, and it is why we schedule extraction jobs earlier in the day when we can.
The practical version: if you park outside and have leather, the protection add-on is genuinely useful. If you park outside and have cloth, a fabric protectant and drying your mats outside the car does more than any product you can buy.
A sunshade, unglamorous as it is, outperforms every interior protectant on the market for keeping a dashboard and a set of seats alive.
