Hey there! Keeping a leather sofa looking its best is a great goal, and you can definitely do it with natural methods. The provided links didn't offer specific cleaning instructions, so I'll share a trusted and simple method based on general expertise.
First things first, you'll want to give your sofa a good vacuuming. Use a soft brush attachment to get into the crevices and remove all the loose dust, crumbs, and pet hair. This step is important because it prevents you from rubbing dirt into the leather while cleaning.
For a gentle and natural cleaning solution, mix equal parts of white vinegar and water in a small bowl. Before you start cleaning the whole sofa, it's super important to do a spot test. Find a hidden area, like under a cushion or on the back, apply a little bit of the solution with a cloth, and let it dry to make sure it doesn't cause any discoloration.
Once you're confident it's safe for your sofa, dip a soft microfiber cloth into your vinegar and water mixture and wring it out well. You want the cloth to be damp, not soaking wet. Gently wipe down the sofa in small sections. For any tougher spots, you can wipe in a gentle circular motion. Afterward, go over the cleaned areas with a second, clean cloth that's been dampened with just plain water to rinse away the vinegar solution.
Finally, dry the sofa completely with a clean, soft towel. Letting it air dry the rest of the way is also a good idea. To keep your leather soft and prevent it from cracking, you can follow up with a natural leather conditioner every 6 to 12 months. A simple DIY conditioner can be made with one part lemon essential oil to two parts linseed oil. Just remember to spot test that as well
