come out = disappear with cleaning
- I spilt wine on my blouse. Luckily, the stain came out when I gave it a hot wash.
- I 'm afraid this mark won't come out of the carpet. Ink doesn't come out easily.
- The colours of the curtains are guaranteed not to come out.
- I have dyed my hair. The colour won't come out for at least ten washes.
- With a high temperature on the washing machine and a strong detergent, all the dirt will come out. Of course, some of the colours might come out, too.
