Do you separate clothes by color before you wash them?

From haier malaysia washing share:

Someone said:

Of course. This makes your clothes look newer and longer. Do not just separate by color, separate from item weight.
Normally, I have:
Ordinary white cotton
Regular cotton colors
Regular dark as training clothes
dress shirts (husband)
towels
sheets
dark heavy items, like jeans and pants.

I became lazy and put delicate things into bags with underwear and threw them into plain washing. I should do it with a lot of material to dry at the same time. In my family there are three of us, so I always do the washing. I also wait, and I will full.

Someone said:

In a sense, I have white and very light colors together, because bedding and underwear, etc. need hot water to really clean them and smell fresh.

I was dark together, so their colors don't run and affect the colors of white clothes.
I keep the towels together because they need a long time to dry.

I wear jeans and heavy clothes, so I save on the bill for the dryer.

Sometimes I wash mixed colors, if it's enough for a full load. The colors are usually not visible, and the pattern is often white, which I would like to look really white and not blunt gray.

I used the bleach from time to time when I had to get rid of the stubborn stain. I only used it on the stain area.

I also dye the costumes in the washing machine. After finishing the load of the colored material, I sprayed the washing machine with an empty bleach and a little detergent to wash off the dye from the washing machine and hoses.
