Tips to Remove Stains with Optical Brighteners
Posted: Oct 26, 2015
Optical brighteners are fluorescent synthetic chemical added to a detergent to make clothes appear brighter and cleaner. It enhances the color of the fabric making it look whiter as it increases the overall amount of blue light reflected from the fabric. It is also helpful in removing stains from different fabrics. Earlier detergents used bluing to give better cleaning and to increase brightness of the fabric, which are now replaced by detergents with brighteners in them. These brighteners can be used on natural fabric such as cotton as well as for synthetic fibers and polyester. Different stains need to be treated differently. With the below mentioned tips, you can remove almost all types of stains.
It is always better to treat the stain immediately as this increases the chance of it being removed completely. The more a stain sits on the fabric, the more it gets absorbed making it tough to be removed.
Soak and Pre-wash
For tough stains like human stains such as urine, saliva or sweat, it is required to soak the clothes and pre-wash them with a detergent at low water level for a few minutes. Rinse thoroughly and then wash the clothes with an optical whitening agent for maximum brightness and whiteness.
Stains of Food and beverages
When working on removing stains of food and beverages like those of ketchup or coffee, pre-wash the fabric for 3 to 5 minutes in hot water at low levels because at low level, the detergent is able to work effectively on the stains. Wash the fabric with an optical whitening agent and rinse properly. It is recommended to not to dry the garment until stain is removed completely as this might set the stain in the cloth thus making it difficult to be removed later.
To clean the stains of mud first scrape off whatever maximum is possible. Soak the fabric and rub in water before washing. For tough stains, soak the cloth in detergent for around 30 minutes, wash normally and if the stain still persists, soak for another 30 minutes and then wash thoroughly.
