Example Input: [header] How to oil a saddle [title] Warm the oil. [step] Before you begin oiling your saddle, be sure to warm your oil. The oil needs to be warm (at most 100 degrees fahrenheit or 38 degrees celsius), but not hot. <sep> (A) If you're not used to warming the oil, start with just a tablespoon of oil or butter. Increase the amount, at most, until the oil turns a light amber or orange. (B) Thus, warming it yourself can help keep it lubricated, especially if you have dry skin. [substeps] Add your oils to one gallon-sized basin, cover with warm air, or place in your riding house. (C) Hot oil can cook your leather and ruin it. In order to guarantee that it's the right temperature, try soaking it in lukewarm water for about 20 minutes. (D) If you leave the oil unattended, it can become hard and dangerous for your horse. Use a softened saddle oil that's made of cold or moisture that can repair old saddles, such as saddle powder, saddle balm, or castile soap.
