Washing machine tips

Pre-treat obvious stains Act fast and rinse stains in cold water before they have a chance to set. Check the fabric before removing any stain. Do not rub stains as rubbing may push the stain further into the fabric. Avoid hot water on an unknown stain - hot water sets many stains. Avoid the use of any chlorine bleach unless the garment tag says it may be used.

Washing tips

Washing tipsChoose the right water temperatureCold (20C) Ideal for fabrics that might shrink or fade in warm water and recommended for typical wash-and-wear items. Cold Power liquid and powder is specially formulated for cold water washing. Warm (35C) Recommended for permanent press items including light to medium colors. Hot (55C) Provides maximum cleaning for items that can stand hot water without losing color or shrinking.

Washing tipsAvoiding detergent residueDetergent residue is often the result of detergent not being properly dissolved before the wash. In other cases, placing washing on the surface of a full machine before adding detergent can cause air pockets to form under the washload. Lumps of powdered detergent are more difficult to dissolve. To prevent lumpiness, store your powdered detergents in a dry area to avoid moisture pick-up

Common problemsMost washing machine problems are some form or conjunction of the following symptoms:The tub will not spinThe machine will not drainThe machine is abnormally noisyThe machine is leakingThe clothes smell bad after the washing
