Conditioning leather after cleaning is like applying a moisturizing lotion to your dry skin after a bath.

Start by lightly dampening a clean washcloth so that it doesn't absorb too much conditioner. (No need to waste a good thing).

Pour or spray on a little Lexol Conditioner...about 2 or 3 half-dollar sized spots...and wipe it onto the leather. A little Lexol goes a long way, and multiple coats are better than one heavy application, unless the leather is very hard and dry.
The entire leather garment should be treated and then allowed 20 to 30 minutes to absorb the oils and preservatives. After this time, use the clean dry towel to vigorously rub down all of the leather surfaces and stitch lines to remove any excess conditioner.
After cleaning and conditioning, the garment should be allowed one to three hours drying time, depending on temperature and humidity.
