Grain Leather Regularly dust or brush with a soft brush, or wipe clean with a slightly damp cloth. Treatment with proprietary cleaners or polishers should be carried out adhering strictly to the manufacturers` instructions. Never use excessive quantities - the less the better. Once a year the leather should be wiped with a cloth slightly dampened with white spirit to cleanse the leather surface thoroughly from old and discoloured detritus. It should then be given a very light treatment with a proprietary polish, and finally rubbed up with a soft clean cloth. Suede Leather Brush regularly with a soft suede brush or rub gently with a plastic foam block. Minor stains and marks may be removed with a hard rubber eraser, or by touching up the surface with a fine emery paper. The leather should retain its colour and appearance if it is regularly treated with a fluorocarbon aerosol spray product. These make the leather water repellent, and offer protection from grease and dust.
