Oil products like olive oil, oil soap and WD-40 can ruin the leather seats in your car, so you should not use them. Old wives’ tales say oil helps soften up and condition leather, but that only works for baseball mitts and cowboy horse saddles – not your nice leather seats.
With dry, dirty or scratched leather, you may find yourself scouring the internet for DIY treatments. Many articles cite olive oil as a cure-all for every leather ailment, from scratches to dryness to odors. It is likely that this myth came from the age old practice of oiling baseball gloves and horse saddles. Oil may have its perks in functionality for those purposes, but we strongly discourage using any type of oil on your fine leathers.
One of the worst things to eat on leather couches is buttered popcorn – yes, the all-time favorite movie snack. What a bummer.
Unfortunately, folks, leather is extremely porous by nature, and it will soak up any oils you put on it – and that includes popcorn grease, lotion and the natural body oils that we all have on our skin. You won’t notice any damage at first, but oils can cause some real trouble down the road.
