    Hi All,

    I have read a few of member's threads who have posted in the past. I though this is mold however I can not clear it.

    Do I need to buy something mold cleaning stuff?

    This wall is along our main bath room till our ensuite. In the past the main bathroom had a leaking water problem when we brought the house which B &P report showed us but the seller fixed it with 10 years warranty. Do you think we need to hire the professional to have a look again?

    Thank you everyone in advance.

    Limescale or surface salt, hit it with some white vinegar.

    That is Efflorescence not mould. You can clean with mild acid solution or get an efflorescence cleaner from Bunnings.
