A small drop of mild dish detergent and warm water is the best cleaning agent for vinyl fabric. With a sponge or clean cloth and soapy water, wipe off the vinyl to remove grim and dirt, food, surface stains. Ensure you do this regularly to ensure there is no lasting build-up of grime.
AVOID using harsh cleaners: never use harsh cleaning solvents or abrasive cleaners on your soft furnishings. When first cleaning with a new product, do a test in an inconspicuous place to ensure no discolouring on the material.
