A few years ago, I cleaned my garden tiles outside with some good product, not only did they become clean but they also bleached nicely. (Quite a strong product indeed).
Now I can't remember what the product was called and I'm Googling myself to death trying to find it. Does anyone know something similar?

Not likely that they were bleached. They probably became as clean and bright as when they were new. Probably something lye-based (high pH) that cleans everything thoroughly.
My tip for you was to use the chlorine solution on the tiles, not on flowers and trees.blob said:
But you are right, one should explain thoroughly.
It should be windless, with a degreasing spray or similar, 1/10 chlorine, the rest water. Be careful with the surrounding vegetation, use safety goggles and a respirator that handles organic vapors. One should absolutely not drink the chlorine solution, if you accidentally take a sip, call 112 immediately and refer to this text.

I was joking with you, you’re right it might not be so suitable with bleach.blob said:
when I flush away the solution it's likely to pass by a flowerbed in one way or another. Or should I let it sit and dry out on its own?
But if you’re careful, it might work if you don't flood with the solution?
And, as you write, it should dry out on its own.

You were right Johan Gunverth. The pressure washer removed the coating and they became bright and nice again - completely without any agents
Chlorine breaks down quite quickly, and if you dilute it thoroughly by rinsing, it doesn't become that environmentally harmful after all...
