Its probably efflorescence

What the builder said...it will dry off and go away eventually.

Efflorescence as Kevin Martin Said - Get some efflorescence remover from him and only use steam at 150 degrees c so as to not saturate the wall which will only bring out more salt

Just leave it it will go away eventually, usually happens on new build walls.

This is an extreme example of what can happen when you  attempt to pressure wash walls down on a house.
I bet that was a bugger to rectify too.
