| (Insert in Rolls-Royce Chassis Instruction Books). CLEANING UNTARNISHABLE SURFACES. On no account should abrasives or polishing preparations of any kind be used for cleaning chromium plated parts, parts made of "Staybrite" steel or other forms of untarnishable finish. The proper course is to treat such surfaces exactly as one would treat high-class, varnished coach-work, namely, wash with clean water and polish with a clean wash-leather. Any other procedure is very liable to scratch the surfaces. Rolls-Royce Ltd., Derby. Leaflet No.4/40/50-20. | ||
