How to wash a white shirt:

Please note that it is best not to put your shirt and jeans in the washing machine.

1.It's best to wash your shirt by hand, and if you really ask the washing machine to help, be sure to put it in a laundry bag;

2.More than 30 seconds is an unacceptable dehydration time for cotton shirts;

3.Adding fabric softener to laundry will make the shirt feel better next time;

4.Cotton shirts should actually be ironed, not folded, and hung directly in the wardrobe.

In addition, when the shirt is stained, you can soak it in cold detergent first, and never use a brush dipped in powder laundry detergent to brush hard, which will destroy the texture of the clothes. If the oil stain is particularly difficult to clean, you can carefully apply a small amount of strong detergent such as white bleach, and rinse off with water immediately after the oil stain has broken down. Do not set the temperature too high when using the dryer, it should be less than 5 minutes.

Dilute it with 84 water and soak it for a long time, and then wash it with laundry detergent, it will easily turn white. However, the concentration should not be too high, otherwise it will backfire.

You go to a larger dry cleaner or laundry and dyeing shop and ask for it, and a skilled dry cleaner will have a solution. Depending on the texture of your shirt, choose a different fluorescent brightener treatment.

This is the most basic and scientific one, and I have learned it in elementary school. White sneakers and white shirts are fine, provided they are cotton. The principle is very simple, there is no absolute white for white, white will always be biased to what color, when it is yellow, it will look old, and blueish will naturally be fresh and the feeling will be very bright.

Therefore, this method is the best, the most traditional and the most scientific, which is a physical phenomenon. As for the use of eighty-four, the effect is good, but the damage to the clothes is great. Unless you don't plan to wear it for a long time, you must always be prepared for rotten, the principle of 84 is that the chemical phenomenon bites off the surface discoloration part, and the clothes will not be strong over time.

It's a great way to go here.
