Felt paper stains on split face block?
My own house as well as a job I’m lookig at both had some water stains occur during construction. Anyone have any ideas how to remove this? I’ve tried pressure washer, Dawn soap and a brush with no luck.

Try a dish washer powder like Electrosol. Mix it in real hot water until no more will dissolve and apply with the chemical injector on your pressure washer. Let it soak 10 minutes or so and rinse. I've had great success getting asphalt stains off metal using this technique but haven't tried it on blocks so your results may vary.
