    I need to clean up a wall but not sure how. I treated it previously with bleach but it didn't clean it. Any ideas?

    Behind the wall is earth.

    Pressure washer. Long term you might be better removing all that white paint and rendering the block work that the paint was trying to cover up.

    Looks like you need drainage holes in the wall because you've got water seepage at the mortar joints.

    I'd drill holes in it you can put some small pipe into the holes to drain water away from the fact of the wall.

    Pressure wash and repaint

    or maybe just leave it fair faced as it will never ever 100% dry out and therefore will always be a damp medium for mould.
    Paint will only stop it drying out.

    Small weep holes will clog up over time so maybe drill 1.5 inch holes along the lowest row of blocks that are on the flat.
    Rather than bleach, there is a mould treatment e.g.

    which will help when the paint is gone and the wall has dried a bit

    I think the white paint was there to cover up the visual difference between the concrete block work and the red brickwork.

    Even though they may be fair faced blocks it might still have looked like they were part of the foundations.
