Well, the provided context is about as useful for cleaning as a screen door on a submarine. One source is just a link to a Reddit conversation, and the other is the footer from YouTube. So, let's toss that aside and get down to brass tacks based on some real-world wisdom.
Tackling those greasy ghosts of snacks past on your sofa arms is a rite of passage for any couch owner. First, before you mix any magic potions, you must consult the oracle: the cleaning tag. Somewhere on your sofa, there's a tiny tag with a letter code (W, S, W/S, or X). This isn't a secret society handshake; it tells you what your sofa can handle. "W" means water-based cleaners are your friend, "S" means solvent-based only, "W/S" means you can use either, and "X" means you're only allowed to vacuum, so maybe just buy some armrest covers and call it a day.
Assuming you have a common "W" or "W/S" fabric, start by vacuuming the area to evict any crumbs and dust bunnies. Then, create a gentle brew of a few drops of clear dish soap in a bowl of warm water. Get a clean, light-colored microfiber cloth, dip it in the suds (not the water!), and gently blot the stain. Don't scrub like you're trying to erase a bad memory; that just grinds the grime in deeper. Work from the outside of the stain inward to prevent creating a sad, smudgy halo.
Once you’ve blotted the stain into submission, take a second cloth dampened with just plain water and blot again to "rinse" the soap out. Finally, press a dry towel onto the spot to soak up as much moisture as possible, then let it air dry completely. If you're dealing with an "S" code fabric, a cloth lightly dampened with rubbing alcohol is often your best bet, but always, always spot-test in a hidden area first. You wouldn't want to turn a small stain into a giant, bleached-out catastrophe.
