Accidentally spilling custard on your outdoor sofa fabric can be frustrating, but don’t worry—there are effective ways to tackle the stain. First, gently scrape off any excess custard with a dull knife or spoon. Avoid rubbing, as this can push the stain deeper into the fabric. Next, mix a solution of mild dish soap and warm water. Dab the stained area with a clean cloth soaked in the solution, working from the outside inward to prevent spreading. Rinse with cold water and blot dry. For stubborn stains, a mixture of white vinegar and water can help break down the residue. Always test any cleaning solution on a hidden area first to ensure it doesn’t damage the fabric. Regular maintenance and prompt action are key to keeping your outdoor sofa looking fresh.
