Vintage coach soft bucket nubuc 4943

Vintage coach soft bucket nubuc bag in fair condition due to the stains shown in the pictures. I am not sure what the stains are being I bought this used. I am not very familiar with this leather on how to remove it. Other than the stains, I see no other significant flaws such as holes or tearing leather. The leather is very soft. The measurements are available in the coach catalog picture. The strap is adjustable. I believe the color of the bag is sand.
