Hello,
On the armrests of your leather sofa and on the head, you see sebum spots. Sebum is naturally secreted by the human body and tends to accumulate to form stains. In some cases it may saturate the leather until it tears. To get rid of it, apply our sebum cleanser, leave it on for a few moments, dry, and repeat many times over several days. If possible, apply it to the back of the skin as well. It is essential not to neglect this step because sebum (greasy substance) and our products (water-based) do not mix well.
Once healthy and completely defatted with acetone you can spray our spray dye for sofas and club chairs, here is our range of colors, you will get beautiful natural shades.
Then, apply our patina wax to protect the leather and give it a "candle" feel.
Good renovation.
