Ah, the age-old question of whether to give your leather sofa a hot, steamy spa treatment. While the idea might sound wonderfully purifying, it's generally a path you want to avoid, lest your sophisticated lounger end up looking like a dried-up prune.
Based on the spirited discussions you'd find in a place like the provided Reddit leather community, the consensus is a resounding "please, for the love of all that is supple, do not do that." The combination of high heat and moisture from a steam cleaner is a fantastic way to strip the natural oils right out of the hide. This can lead to the leather drying out, cracking, and suffering from discoloration. You're essentially speed-running the aging process, and not in a distinguished, fine-wine sort of way.
While one of the sources provided is just the generic footer from a YouTube page—about as helpful for leather care as a chocolate teapot—the sentiment from leather enthusiasts is crystal clear. You risk damaging the protective topcoat and turning your investment into a regrettable, crispy mess.
Instead of unleashing a steam-powered dragon on your furniture, opt for a gentler approach. A soft, slightly damp cloth can handle most light cleaning. For tougher jobs, a cleaner specifically formulated for your type of leather is your best friend. Follow that up with a good leather conditioner every so often to keep it hydrated and happy. Save the steam for your shirts and your sinuses; your sofa prefers to keep its cool.
