Vegetable tanned leather may have no finish or may have a finish however it is more likely to 'dry out' than chrome tanned leather. Traditionally vegetable tanned leather is cleaned using saddle soap and treated with oils such as neatsfoot oil, dubbin or coachaline.
The use of Leather Wax, which contains natural bees wax, natural carnauba wax and neatsfoot oil together with a water repellent agent is recommended for vegetable tanned leather. Also recommended for work boots to waterproof & prevent cracking.
