You could try using water, a vinegar dilution and rinse or perhaps a dry brush. 
Alternatively there are chemicals specially made for this online. Check to see if compatible with lime mortar

Brick acid will react with the lime . Try a wire brush -then some linseed oil on a cloth and add to the brick  face . 
Why is the wall getting wet ? Is the gutter secure and leak free above it? 
,,Rain does not penetrate brick more than 2-5mm - and in a house wall like yours it drys within hours of the rain stopping - so look for gutter leaks running down the wall or damp rising in water logged areas .
It will only leach salt -if it is constantly wet ,,notice -it will stop when it’s dryer weather. -the linseed darkens the brick - but it also stops surface evaporation causing a draw of moisture through the brick and as such raising the salts to evaporate on th e face -  and dry in the wind . .
At ground level - make sure soil is clear from the wall base -so not to supply -
by candle wick effect -water to the bricks .
