Super Simple Tack Cleaner: Mix 1/2 cup olive oil with 1/4 cup vinegar in a spray bottle. Strip tack and take apart all pieces. Shake spray bottle well and often. Liberally spray leather with solution and buff with a clean, soft cloth. Once dry, reassemble pieces. The vinegar gently cleans and kills mold and mildew spores, while olive oil is a great leather conditioner. Also works on wood.
