Proprietary leather cleaners – Commercially produced cleaners are commonplace with leather care, but can have negative effects if not closely researched or familiar with the ingredients. Wet cleaning and solvent cleaning – The primary purpose of any wet cleaning on leather is to remove surface soiling. Leather should not be soaked in water.
wetting back- semi-processed leather is rehydrated. sammying - 45-55%(m/m) water is squeezed out the leather. splitting - the leather is split into one or more horizontal layers. shaving - the leather is thinned using a machine which cuts leather fibres off. neutralisation - the pH of the leather is adjusted to a value between 4.5 and 6.5.
Wet cleaning machines have controls that allow them to safely and efficiently clean a wide variety of garments in water. Detergents and spot removers are made of ingredients that are safer for workers and the environment, yet are as safe and effective at removing soils, stains and odors as dry cleaning solvents.

The amount of leather fibers in the mix varies from 10% to 90%, affecting the properties of the product. [11] The term "genuine leather" does not describe a specific grade.
A leak in the head gasket - often called a "blown head gasket" - can result in a leak of coolant, the combustion gasses, or both. Blue smoke from the exhaust suggests that excess oil is entering the combustion chambers (although there are other possible causes than a head gasket leak). White smoke from the exhaust suggests that coolant is ...
A washing machine can have an impeller, also called a wash plate, instead of an agitator, which serves the same purpose but does not have a vertical cylinder extending from its base. Since the agitator and the drum are separate and distinct in a top-loading washing machine, the mechanism of a top-loader is inherently more complicated than a ...
