My patio stones (red brick) are now almost 20 years old and have developed many stains from fungi and lichens. I have cleaned them with a pressure washer, but it barely made any difference. How can I remove this unpleasant "patina"?

Especially after winter, there are ugly stains on the stones. I got this product from sports field construction, and the good thing is that it does not damage the stones.
The subfloor must be dry, and I let it sit for about two hours. After that, rinse thoroughly. Then it looks good again.
