Accumulated road dirt and mud must never be rubbed or brushed off dry from enamelled parts as the abrasive nature of the dirt will scratch and dull the surface of the enamel.
Always wash off dirt by means of liberal supplies of water, if possible from a hose pipe, but do not employ a high pressure jet.
The water should be set to run at a slow rate so that it does not penetrate where it can do harm, such as into the brakes or items of the electrical equipment and carburetter.
Use a soft cloth or sponge to mop off the dirt when it is properly loosened by the water.
If water is used from a bucket a little household detergent washing powder (such as " Tide ") may be mixed with the water and will help to remove oil or grease.
Dry off with a leather and polish with one of the many polishes now on the market. Chemico "49" will give a high finish which remains waterproof for quite a good time. Proprietary polishes, however, are not a substitute for cleaning and will not give a proper finish unless the surface is properly cleaned first.
Aluminium parts, such as the engine and gearbox, may be cleaned with paraffin and a stiff brush, and afterwards with petrol. These parts are best cleaned before the enamel is tackled.
All plating is porous, and although chromium is rustless, the surfaces of plated ferrous parts will deteriorate if neglected and left exposed to the weather, due to rusting of the metal underneath the plating.
Whilst still clean therefore, the plated parts of a new machine should be wiped over with a rust preventative which will penetrate the pores in the plating. To prevent the attraction of dust through leaving the surface 'greasy' it can be wiped clear after application. We recommend Rust-Veto Amber X ' obtainable from the Service Department. Ordinary grease or oil are not as effective and in some circumstances can cause rusting.
Do not use anything abrasive, or ordinary metal polish, to clean the plating, and do not wipe off dirt that has dried on. Wash clean with soap and water, dry thoroughly afterwards, and then polish with F.L.P. (Supplier, G. H. White, Lowestoft Road, Gorleston, Norfolk).
Apply " Rust-Veto ' as described above.
