Short answer
Protect leather in winter by cleaning off salt and grit, conditioning with a quality water-based conditioner every four to eight weeks, avoiding wet boots on the seats and not blasting seat heaters on dry leather. Clean and condition before the cold sets in for the best result.
What winter does to leather
Leather is a skin that needs a little moisture and flexibility to stay in good shape. Winter works against both.
- Cold makes leather stiff, so it creases more sharply when you sit on it.
- Dry cabin heat pulls moisture out of the leather, and it shrinks and cracks over time.
- Heated seats speed that drying process, especially on older leather.
- Salt and grit from boots and jeans act like fine sandpaper on the surface and on the stitching. Salt also draws moisture out.
- Wet clothing and snow leave water marks and encourage dye transfer from dark denim onto light seats.
Most modern car leather is coated, with a thin protective finish over the hide. That coating takes the abuse, and when it wears you see shiny patches, rough spots and cracks, especially on the driver's side bolster, where you slide in and out. For general upkeep, see our leather seat care guide.
Before winter: clean and condition
The best time to prepare is in fall, before the first heavy salt. Leather needs to be clean before it is conditioned, otherwise you seal dirt in.
- Vacuum seams and creases with a soft brush attachment. Grit in the seams wears the stitching.
- Clean with a pH-neutral leather cleaner on a soft brush or towel. Work in small sections and wipe the residue.
- Let the leather dry fully, then apply a thin coat of conditioner with an applicator pad.
- Leave it to absorb for the time on the label, then buff off any excess. Greasy leather is a sign you used too much.
Choose a water-based conditioner rather than a heavy oil or petroleum product. Oily products can darken leather, make it slippery and break down the finish over time. Conditioner is not a coating, and it does not make leather waterproof, but it keeps the surface soft.
During winter: simple habits that help
- Brush off boots before getting in, and use rubber floor mats to catch slush. See the floor mat cleaning guide.
- Wipe seats every couple of weeks with a barely damp microfibre to lift salt dust.
- Warm the cabin gradually. Blasting heat at the seats the second you start the car, with the leather stone cold, is hard on it. Let the car warm up a bit first.
- Use seat heaters in moderation. They are fine, but constant high heat dries leather out more.
- Condition every four to eight weeks, depending on how dry the car is and how much the seats are used.
- Watch for dye transfer. Dark jeans on pale leather deposit colour. Wipe it off early with a gentle cleaner.
Avoid using wipes with alcohol or household cleaners, which strip the finish. And do not park with the seats in direct sun through glass on a bright winter day for long periods, since UV still fades and dries leather.
What not to do
- Do not scrub hard on cracked or worn leather. You will take the finish off.
- Do not oversaturate. Too much conditioner leaves a sticky film that collects dust and salt.
- Do not use baby oil, olive oil or home remedies. They can darken leather and go rancid.
- Do not ignore small cracks. Conditioning slows the progress but does not repair a crack. Deep damage needs a leather repair specialist, which we do not offer.
Winter also exposes the weak spots in a leather interior. The driver's seat bolster, the steering wheel and the armrest are the first places to show wear, so give those areas a little extra attention when you clean and condition. Catching early wear is far cheaper than dealing with it once the finish has gone.
Perforated leather needs extra care. Excess product blocks the holes and can affect seat ventilation. Use less, and apply it with a pad, not a spray. Seat covers made of synthetic leather or vinyl are tougher but still benefit from regular cleaning.
Letting Jay's handle it
If you would rather not spend an evening on your seats, we can do it as part of an interior service. Interior Restoration starts from $119 $149 and includes a deep vacuum and steam, carpet and seat shampoo extraction, a leather clean and condition, glass, trim and console, and takes about 2 to 4 hours. For the details on how we treat leather see leather cleaning and conditioning and interior detailing.
For many people, the best timing is late October or November, with the car tidy before the salt. We are mobile and work in driveways, office lots and condo garages in Burlington, Oakville, Milton and Hamilton. Our guide to fall car prep before winter has the rest of the list.
