This approach is currently quite popular. Old bricks, preferably with brands, numbers, or other markings, are sometimes traded at high prices and then reused as fireplace surrounds, decorative walls, etc.
Sandblasting or similar. It is a tedious job, but genuine fortunes are currently paid for vintage clinker bricks. From €50 upwards per square meter (even vintage clinker slips from, for example, Celina cost €80 per square meter). Recycling is worth it.Are there machines that clean bricks? I imagine that to be too labor-intensive.
On the one hand, that does not answer my question whether you are asking this purely academically or if you are facing a concrete demolition project. On the other hand, you should google "Trümmerfrauen" and also first acquire basic knowledge about recycling (and while doing so consider the ecological footprint of the respective methods). The crucial point for the difference between re- and downcycling lies in the purity of the materials fed into the process; and in this sense, your hoped-for building material would have the flaw of inhomogeneity – it would unfortunately have to be re-fractionated with high (including energy) expenditure at the next stage, which would only be downcycling. Furthermore, because of its vaguely defined composition, it could not be input into any U-value calculators and practically could be used for no building subject to energy saving regulations. So it would be a building material only for sheds and free-standing garages. Upon closer inspection, you would thus get quite the opposite of what you hope for: planned solution, created problem :-(

Do you mean using a pressure washer maybe? I have already cleaned all sorts of things with our pressure washer, haven’t tried it on bricks yet, but on driveways and sidewalks stained with paint and construction mixture.Are there machines that clean bricks? I imagine that to be too labor-intensive.
