How to use the washing machine?
Washing machines are very convenient and easy-to-use household appliances, but they take some getting used to. If you’ve just received your first dress, or are about to make your first dress, fear not. You can easily learn how to use a washing machine, learn which detergent and fabric softener is best for which type of clothes, and prevent clothes from discoloring or damaging whites.
Check the label for special washing instructions.
Most fabrics are machine washable, but be sure to read the label for more instructions. Always check labels carefully.
Set aside clothes marked “Hand Wash Only” or “Dry Clean Only.”
On most shirts, the garment label is located on the inside left side of the shirt or on the inside of the neck.
Most pants have a garment tag on the inside of the back.
Sort clothes by color.
The color of clothes, especially new clothes, fades after washing. Color can transfer to other clothing and damage your entire load.  Classifying waxes by “color” usually means distinguishing them by color. The easiest way to organize your clothes is to separate dark clothes from light ones and wash them separately. You can even sort them by color more carefully.
Dark colors include colors such as black, gray, navy blue, deep red, and dark purple.
These lights are available in pastel colors such as white, pink, yellow, light blue, light green and lilac.
White includes everything that is 100% white. Avoid washing white flowers with other light colors, as they can discolor.
Jeans or dark denim are particularly prone to bleeding and should be washed separately.
Sort clothes by fabric weight.
Additionally or alternatively, you can prevent clothes from tearing in the washing machine by separating heavy items from light items. Most washing machines wring and discard laundry, and overweight items can damage lightweight items. If you are washing delicate items or a light load, the programme settings and temperatures will also be different than when you wash a heavy load.
Delicate items such as underwear, tights and washable silks should be washed separately. 
Heavy clothing includes heavy cotton pants, bath towels, jackets, or sweaters.
If you choose to sort by fabric only, you will save a lot of effort and money by washing many different colors.
Put fragile items in a mesh laundry bag.
Instead of washing delicate items separately, keep them in a mesh laundry bag to protect them from abrasion. Mesh laundry bags come in a variety of sizes, but are typically used to protect one or more garments. They can be washed with normal loads.
Mesh laundry bags do not protect clothes from fading, so be sure to wash them in a similar color.
