If your cushions are removable, you lucky duck, check the tags for cleaning codes. “W” means use water-based cleaner. “S” means only solvent (specialty cleaner). “S-W” means you can use either, but the sofa still judges you. Never, ever toss a leather cushion in the washing machine. That’s how you end up with a sad, wrinkly leather raisin.
Surprising fact: Leather is not waterproof. It’s more like your skin—it breathes, it absorbs, and it gets cranky if you ignore it. So after cleaning, condition that bad boy with a leather conditioner. Rub it in like you’re giving the couch a spa massage. This prevents cracking, which is leather’s version of wrinkles.
