Hello everyone!
Our construction work on and within 2 meters (6.5 feet) around the house is finally completed...

Of course, this has left some dirt on the brickwork. Among other things, there are still white paint splatters from the painter who plastered and painted the upper floor white...

What is the best way to clean our brickwork?

It is a Röben Brighton Kohle brick, which unfortunately is NOT acid-resistant!

Does anyone have specific product recommendations or cleaning methods?

I would really appreciate any advice.

Try using vinegar or cola.
It’s best to test first on a less visible spot.
Soak the brick first, then rinse thoroughly.
You might also try using heavily diluted hydrochloric acid, but be careful because of efflorescence.
Choose a small area where you will need to do some filling anyway.

Vinegar, hydrochloric acid?
As you already said, efflorescence is almost guaranteed.
A hundred years ago, this was commonly done on hard-burnt bricks. Today, anyone attempting this needs a lot of courage.
