First, you’ll want to get rid of the stains as soon as possible. Doing so prevents the coffee from permanently discoloring your upholstery. Start by gathering:
Start by soaking up as much liquid as possible with a clean towel or chamois cloth. From there, mix dish soap, white vinegar, and warm water to create a cleaning solution. Blot the solution gently over the stained areas, and remember to dab, not rub. This solution should also help with any lingering odor.
If this does not completely remove the stain, try mixing one tablespoon of laundry detergent with a cup of warm water and repeat the application process. Be sure to wash all soap from the seat with warm water and absorb excess moisture with another clean cloth.
Best of luck, and enjoy PSL season safely!
