When beverages are permitted near a leather couch, spills occasionally occur. When that spill is a sticky substance such as soda, it can leave behind quite a mess if not dealt with right away. If the spill occurs on a removable cushion, check the areas between and under the cushions to ensure more soda isn’t hiding in these obscured areas.
Blot up baking soda with paper towels, with several stacked or folded paper towels at a time for added absorption. Discard the moist towels and keep blotting with warm towels until all of the liquid has been absorbed.
Inspect the region between the couch cushions to find out if any of the soda spilled there. Lift a removable cushion and wipe any evident soda using a dry paper towel. Twist the region under the cushions to find out if it also takes a paper-towel blot therapy. Wipe up all of the moist areas with a dry paper towel.
Wipe the affected areas gently with a damp white cloth, wiping from the exterior of the spill region toward the inside; this helps keep any dyes in the soda from spreading. Pat dry with a fresh white cloth.
Mix one or 2 squirts of liquid castille soap or saddle soap into a quart or so of water. Dip a soft white cloth into the soapy liquid, then wringing out most of the moisture. Wipe the spill region with the damp rag, wiping in the outer borders of this spilled soda toward the center of the spill. Wipe with a fresh damp cloth, followed by a dry cloth. Permit the couch to dry before sitting to the affected area.
