Here is a question you likely don't see very often.

Old house that formerly had a coal bin. Cinder block wall
blackened from the coal. What is a good cleaner that won't harm
the wall?

After cleaning per Greg Z, a couple of coats of a latex paint applied
with a long roller should penetrate into the blocks and seal them
pretty well.

Even better would be to clean the walls using a pressure washer and
some means of catching the dirty water, and then allowing to dry
thoroughly for several days, and then applying paint using a pressure
washer to get the paint deep into the cinder blocks. You don't say
that the wall is "wet", so I'm assuming that water seepage is not a
problem.

Pressure washer with paint?

Look forward to seeing the You Tube video
