Step 1
Abstain from regular cleaning. If you don't mind waiting several months to transform the leather from shiny to dull, you can simply let natural wear and tear diminish the product's shine. Normally, leather furniture is cleaned two to four times a year to prevent natural skin oils and friction from affecting the original finish.
Step 2
Strip the shine from the leather by using sandpaper, a common aging technique for leather. Gently rub very-fine-grit sandpaper over the entire surface of the leather furniture to diminish its luster and give it a dull, slightly weathered appearance.
Step 3
Add a small amount of nail polish remover to a sponge and rub it across the leather. Leather made shiny with wax or chemicals will be stripped of its shine by the nail polish remover.
Step 4
Spray matte finish for leather on the surface of the leather and allow it to dry, and the finish will be transformed from shiny to matte.
