Soap-treated Oak: It should be treated 2-3 times in the first three weeks of use to allow the soap to penetrate the surface and keep it light in colour. Subsequently, it should be treated approximately every 2-3 months if it becomes too dark, dry or dirty. The soap mixture should be applied with a wrung soft sponge or cloth, in the direction of the grains, evenly and without leaving any spots, stains or thick lines. The sponge or cloth should then be rinsed and well wrung before being used to dry the surface. It is normal for the fibres of the wood to raise slightly after the first couple of treatments. When the wood is dry, sand gently in the direction of the grains with fine grain sandpaper (180–240) or a sanding-sponge. Wipe away any dust. Leather: Avoid placing leather in direct sunlight or extreme heat. Clean using the suds from household soap flakes. Mix 50 ml. soap flakes to one litre of hot water. When the water is room temperature, apply the foam over the leather with a soft cloth. Avoid soaking. When dry, polish the leather with a clean cotton cloth. • Avoid contact with sharp objects. • Absorb spills immediately with a clean, dry cloth. • Vacuum regularly with a soft brush to remove dust. • Never use detergents, ammonia, oils, polish or varnish.
