While some people look down on wearing fake leather as a cheap alternative lacking the luxuriousness and superior appearance of real leather, it does have advantages. Faux leather, being a synthetic product, protects animals from being used in shoes or garments. Faux-leather products typically come in a wider variety of colours as well. However, like just real leather, faux leather sometimes squeaks when worn.
Dab a nickel-sized amount of mink oil onto a lint-free cloth. Rub the oil all over the synthetic leather. Conditioning will remove the typical sticky feeling of faux leather products, which can exacerbate squeaky sounds.
Allow the items to sit or hang in fresh air away from direct sunlight for at least 12 hours. This will allow the oil to absorb into the product.
Purchase a foam shoeshine-polish sponge in a colour that matches your fake leather. Run the sponge over the entire surface area of the item, even if it's not a pair of shoes. This will further buff the material, removing any unabsorbed mink oil and stickiness. Your faux-leather item should now be squeak free.
