First of all, you must thoroughly read the labels attached with the article of clothing. They tell you about the material used to make the cloth, and the way to wash it. The labels usually give you very important information about the way to remove the stains.
Having done so, try to getting rid of the stain by using a sponge or something of this nature. It must be done before washing. There is a possibility that the sponge sucks out the stain and you may not need to wash the article.
If the sponge trick does not work, use a Stain Removal stick. There are many stain removals sticks available in the market and sometimes they work well. Washing is no good for the clothes; therefore, try every possible way prior to that.
It is best to use a dry cleaning solvent for clothing, such as Dacron, or a high polyester article. This procedure hardly affects the dress.
If nothing works, go for the water cleaning. But always use a good reputable detergent, containing enzymes. Such detergents are expensive, but nothing is more important than your dress, especially if it is a new one.
Don’t use too much quantity of the detergent. After applying it on the cloth, rub the damaged part gently with your hands. Keep rubbing it smoothly until the stain is gone.
Wash the article with clean water and let it dry itself. There is no need to put it in the dryer.
