These are the major uses of Neatsfoot oil.
Neatsfoot oil for Leather products
Take a small amount of neatsfoot oil and warm it up slightly, especially if it has solidified. Then massage it into the leather product after it has been cleansed. This darkens the appearance of leather. After some time, the oil is absorbed into the leather. It penetrates deep into the micro-structure of leather, rejuvenating its shine and appearance. Neatsfoot oil should be applied to condition leather products, like jackets, boots, shoes, saddles, coats and belts.

One can make use of this to polish furniture, cutting board and other wooden products, even the entire deck.
Neatsfoot oil for Oil Painting
Neatsfoot oil is a wonderful oil for oil painting. It doesn’t dry quickly. It is used to clean the metal part of brushes off paint that stays there as a residue. This acts as an impurity when picking up new paint which is undesirable. Neatsfoot oil dissolves away this impurity, rendering the brush absolutely clean.
The pure neatsfoot oil is a good product for skin applications.
Relieves Dry Skin
100 % pure neatsfoot oil obtained from lard ( pig fat ), or from cattle foot and bones can be applied on the skin. It takes care of dry skin, effectively moisturizing. Animal based oils and products have been used since ancient times as healing agents . Their prominence has declined in modern times, but they can still be effective in treating many skin conditions. Neatsfoot oil, which is an animal derived product is also an excellent skin emollient. But, one should make sure that the oil is of high quality, free from harmful fillers.
Protect skin from harsh winter
Our skin suffers a lot in harsh winter months. The dry air and very cold climate makes the skin dry. Extreme cold temperatures, like in the Arctic circle can make the skin extremely numb, reducing blood flow which puts the body part at risk for damage. Applying neatsfoot oil all over the skin provides an extra layer of insulation, even when one is wearing warm clothes. It protects the epidermis ( outermost skin layer ) from direct contact with extremely cold air. As a result, neatsfoot oil effectively provides a cushion of a few degrees. Our skin may be well below sub zero temperatures, but still not feel that numb.
This is especially helpful for the old, because the fat layer of insulation in their skin has thinned with aging . This exposes the internal body organs to cold temperatures, which is not good for health. Applying insulating oils helps to keep the body warm in cold.
Research indicates that a diet containing lard increases thermogenesis, that is increased heat production from within the body. This helps the body fight colder climates better. 
Neatsfoot oil is also used for industrial applications. The most prominent one is use as cutting fluid in aluminium machining. Neatsfoot oil, or lard oil controls temperature rise in aluminium when it is being cut to prevent thermal effects on the metal. This process provides a refined and well cut metal.
Side Effects, Safe Dosage and Toxicity Issues
Neatsfoot oil is generally safe to be applied on skin. However, products that are not of good quality and contain harmful additives can be harmful for the skin and overall health.
