Wipe the sofa off with a microfiber cloth, which absorbs the dust and debris from the couch’s surface. Squeeze a few drops of the dish soap into a large bowl and add enough warm water until you have a thick, sudsy mixture.
Dip the terrycloth towel in the solution and ring out the excess liquid. Rub the towel over all areas of the couch, removing any trapped dirt and lifting off stains. Dry the couch with more towels, wiping off any of the soap and water left behind.
Rub distilled white vinegar on any remaining stains. Gently work the toothbrush around the stain, using the pressure and the bristles to lift off the stain. Rub a damp towel over the sofa, removing the vinegar and wiping off the stain.
Mix the liquid repair from the vinyl repair kit. Apply the mixture to any rips or tears in the vinyl. Lay the textured paper from the kit on top of the adhesive mixture and gently run an iron over the paper, using the lowest setting. Apply heat for at least 30 seconds and gently peel away the paper.
Apply the mixture from the kit to any scratches on the vinyl sofa. Cover the mixture with the transfer paper and apply more heat for 30 seconds. Let the paper and adhesive mixture cool and gently peel away the paper. The mixture covers the scratches, making them blend into the surrounding vinyl.
