Fabric Care - General Turn cushions regularly, beat well and plump. Clean treated leather with a soft, damp cloth, and not a detergent. Renew it by polishing with a proprietary hide cleaner every 6 weeks. To protect against clothes moths, avoid leaving fabrics untouched for a long time. Move, clean and air regularly. Avoid the accumulation of dust and fluff where moths can breed. Cedar wood and lavender may be used as alternatives to mothballs. To check if a fabric will run, dampen a corner and iron between white cloth: if the colour shows up on the white cloth, the fabric is liable to run. Stiff silks can often be made floppier by having the natural gum removed in dry cleaning.
