Clean and polish leather furniture with a mixture of white vinegar and linseed oil.
A mixture of white vinegar and linseed oil effectively cleans and conditions leather upholstery and clothing. However, vinegar will not remove mold, mildew, or set-in stains from leather.
Making Vinegar-based Leather Cleaner
To make a vinegar-based leather cleaner, mix 1 part white vinegar with 2 parts food-grade linseed oil, recommends the Mrs. Clean USA website. As an alternative to linseed oil, substitute neat's-foot oil.
Usage
The Vinegar Institute recommends using a vinegar and linseed mixture to buff and polish leather fabrics. Rub the leather into the fabric and allow it to sit overnight, suggests the Mrs. Clean USA website. Wipe away the vinegar and oil mixture with a soft, clean cloth.
