Launderer
Imam Ja‘far al-Sadiq: Seeing a launderer in a dream is interpreted as your being delivered from grief and sorrow, and as indicating that you must repent of your sins.
Ibn Sirin: To see in a dream that you are engaged in laundering, although you are not a launderer in waking life, indicates that you will repent and become a person possessed of piety.
Kirmani: To see in a dream that the garment you have washed has become white is interpreted as your turning toward Allah and henceforth refraining from committing sins; if you have seen the exact opposite of this dream, it is interpreted as your being unable to refrain from sin.
Jabir al-Maghribi: Seeing a launderer in a dream indicates people who perform works directed toward goodness and peace in the path of Allah.
Positive Meaning
It provides early awareness; the person sees risks before they grow and can choose a more solid path.
Shadow Meaning
Neglect, haste, untrustworthy people or uncontrolled behavior can increase the difficulty.
Advice
In the interpretation, the themes of spiritual signs, work and responsibility, the emotional tone in the dream, and how the symbol concludes in the dream should be evaluated together.
