To remove mildew from leather, create a mixture of one-cup rubbing alcohol per one-cup of water. Wipe the mildew area with a cloth dipped in the diluted alcohol, then allow it to dry. If the mildew persists, use mild soap and water that contains a germicide, then remove with a clean dampened cloth and allow to dry.
An important key to keeping leather in top-notch condition is to treat wet leather before it has a chance to dry. Remove any dirt, mud, or other stains with a cleaning agent, then condition while the pores are still fully responsive. It is critical to remember that leather should be dried away from heat.
Remember that leather is a natural material and should never be stored in plastic because it encourages the growth of mildew and bacteria and will ruin the leather. Always store leather in a cool, dry place away from heat.
Fresh stains from things such as blood and food can be cleaned up quickly with a damp cloth. Stains from oil or grease can be lifted by grinding ordinary blackboard chalk, sprinkling the area, and leaving the powder on for a twenty-four hour period. Resist the urge to rub the powder in. After a sufficient time has past, simply use a leather care brush to remove the powder. While fresh stains can be treated and cleaned at home, ground-in stains should be attended to by a professional cleaner who deals in leather.
