Whites should be washed individually. Laundering white objects together in the hottest water the cloth can tolerate is the only way to keep them white (water that is at least 120 degrees is most effective at removing soil). Use the full volume of detergent that contains a bleach substitute and/or enzymes.
Here are some instructions to wash white clothes:
1. Whites should be separated.
Sorting dirty laundry carefully is the first step in keeping white clothes white. White clothing should be washed individually to avoid colour fading and transfer from coloured fabrics, which can dull white cotton.
2. Overloading can be avoided.
It’s tempting to stuff the washer to the brim with clothes, but it won’t get you the cleanest results. When a washer is overloaded, there isn’t enough room between things for the water to flush away the dirt, so the dirt is redeposited on the fabrics, making them appear bland.
3. Select the Appropriate Detergent
Choose a white-clothing detergent that incorporates optical brighteners. They act by deceiving the eye: ultraviolet light waves are bent to highlight blue light while reducing yellow light, making fabrics look whiter. However, don’t assume that using more detergent would improve the performance. The excess detergent will cling to cloth fibres, attracting dirt.
4. Treat stains as soon as possible.
Follow the stain removal instructions for each fabric and stain sort. Although chlorine bleach will whiten, it can also ruin fabrics if used excessively. OxiClean, Nellie’s All-Natural Oxygen Brightener, or OXO Brite are all oxygen-based bleaches that can be used on all washable fabrics except wool and silk.
5. Wash with the warmest water you can find.
To help dissolve body oils and grime that can dull the cloth, use hot water—or the warmest water recommended for the fabric. Depending on the nature of the stains or discolouration, wash on a regular or heavy-duty setting.
6. Rinse With Vinegar
Skip commercial fabric softeners, which can leave residue on white fabrics. Instead, add 1 cup distilled vinegar to the rinse cycle to ensure that all the detergent is stripped away from fabrics.
7. Examine The Garments
Before putting the clothes in the dryer, double-check each one. If the marks persist, reposition the spots and wipe them again. Drying a stained fabric on high heat may cause the stain to become permanent.
8. Low-heat drying
The visibility of white garments and fabrics can be greatly improved by drying them outdoors. The sun’s ultraviolet rays will help to whiten and freshen your skin. If drying outdoors isn’t an option, use a dryer on a low heat setting to dry your clothes. Remove wet clothes from the dryer and air-dry them on a drying rack.
