You can get food laundering results if you sort clothes according to the following guidelines:
Separate colors and whites into different laundry loads. Intense colors (very bright or very dark) may bleed, especially when washed for the first time. They can tint white or light-colored clothes washed in the same load. A good guide is the maker’s care label.
Separate chlorine-bleachable light and white clothes from those that cannot be bleached if you intend to add chlorine bleach to the wash.
Most wash loads do quite well in cold or warm water. Heavy soils on cotton respond better to a hot-water wash. Hot water may have an adverse effect on permanent-press garments. Check each garment’s care label.
Separate very dirty clothes that should be presoaked or washed in hot water from lightly soiled or temperature-sensitive items.
Separate sweatshirts, new towels, and products made from chenille yarn (all of which may tend to generate lint) from permanent press clothes and corduroys (which attract lint).
As you sort wash loads, remember to empty pockets and close zippers to prevent snagging. Next, check for troublesome stains that may have become set. Some stains won’t respond well to a presoak or laundry booster alone, and require special treatment before washing.
To keep socks from getting lost, place them at the bottom of the washing machine tub, wash them in a mesh bag, or use sock savers, plastic rings designed to lock pairs of socks together.
Do not overload your dryer. Always allow ample room for articles to tumble about freely. Placing too many items in a dryer can lengthen drying time and cause garments to wrinkle. Leaving clothes in the dryer’s drum after tumbling has stopped can also cause wrinkling.
To ensure optimum drying time, be sure to clean the dryer’s lint filter after each use.
