Removing wrinkles helps restore the natural luster of rubber. Rubber objects can act as a protective layer atop valuable and fragile materials and are also useful as safety devices. Rug mats, for example, are often made of rubber and slid underneath fabric rugs to prevent slipping and sliding. The trick to removing wrinkles from rubber is to incorporate heat into the flattening process. Heat will cause rubber to bend and cooperate with its reforming.
Items you will need
Place the rubber onto an ironing board. Notice the direction of the wrinkles.
Plug in the iron. Add water to the prefabricated opening to create steam. Flip the iron to the "Wool" setting. Turn the iron on.
Run the hot iron slowly over the rubber in the direction of the wrinkles. Squeeze the iron handle to generate steam to moisten the rubber, allowing it to stretch. Move the iron with the direction of the wrinkles to flatten the rubber back out into its natural shape. Running the iron against the wrinkles in any way may result in uneven flattening. Avoid overheating the rubber to prevent melting.
